Welcome to the ELB Guide to English Word Order and Sentence Structure. This article provides a complete introduction to sentence structure, parts of speech and different sentence types, adapted from the bestselling grammar guide, Word Order in English Sentences. I’ve prepared this in conjunction with a short 3-video course, currently in editing, to help share the lessons of the book to a wider audience.

Different Ways to Analyse English Structure

There are lots of ways to break down sentences, for different purposes. This article covers the systems I’ve found help my students understand and form accurate sentences, but note these are not the only ways to explore English grammar.

I take three approaches to introducing English grammar:

• Studying overall patterns, grouping sentence components by their broad function (subject, verb, object, etc.)
• Studying different word types (the parts of speech), how their phrases are formed and their places in sentences
• Studying groupings of phrases and clauses, and how they connect in simple, compound and complex sentences

Subject-Verb-Object: Sentence Patterns

English belongs to a group of just under half the world’s languages which follows a SUBJECT – VERB – OBJECT order. This is the starting point for all our basic clauses (groups of words that form a complete grammatical idea). A standard declarative clause should include, in this order:

• Subject – who or what is doing the action (or has a condition demonstrated, for state verbs), e.g. a man, the church, two beagles
• Verb – what is done or what condition is discussed, e.g. to do, to talk, to be, to feel
• Additional information – everything else!

In the correct order, a subject and verb can communicate ideas with immediate sense with as little as two or three words.

• Gemma studies.
• It is hot.

Why does this order matter? We know what the grammatical units are because of their position in the sentence. We give words their position based on the function we want them to convey. If we change the order, we change the functioning of the sentence.

• Studies Gemma
• Hot is it

With the verb first, these ideas don’t make immediate sense and, depending on the verbs, may suggest to English speakers a subject is missing or a question is being formed with missing components.

• The alien studies Gemma. (uh oh!)
• Hot, is it? (a tag question)

If we don’t take those extra steps to complete the idea, though, the reversed order doesn’t work. With “studies Gemma”, we couldn’t easily say if we’re missing a subject, if studies is a verb or noun, or if it’s merely the wrong order.

The point being: using expected patterns immediately communicates what we want to say, without confusion.

Adding Additional Information: Objects, Prepositional Phrases and Time

Understanding this basic pattern is useful for when we start breaking down more complicated sentences; you might have longer phrases in place of the subject or verb, but they should still use this order.

After subjects and verbs, we can follow with different information. The other key components of sentence patterns are:

• Direct Object: directly affected by the verb (comes after verb)
• Indirect Objects: indirectly affected by the verb (typically comes between the verb and a direct object)
• Prepositional phrases: noun phrases providing extra information connected by prepositions, usually following any objects
• Time: describing when, usually coming last

The individual grammatical components can get more complicated, but that basic pattern stays the same.

The phrases making up each grammatical unit follow their own, more specific rules for ordering words (covered below), but overall continue to fit into this same basic order of components:

Subject – Verb – Indirect Object – Direct Object – Prepositional Phrase – Time

Alternative Sentence Patterns: Different Sentence Types

Subject-Verb-Object is a starting point that covers positive, declarative sentences. These are the most common clauses in English, used to describe factual events/conditions. The type of verb can also make a difference to these patterns, as we have action/doing verbs (for activities/events) and linking/being verbs (for conditions/states/feelings).

Here’s the basic patterns we’ve already looked at:

• Subject + Action Verb – Gemma studies.
• Subject + Action Verb + Object – Gemma studies English.
• Subject + Action Verb + Indirect Object + Direct Object – Gemma gave Paul a book.

We might also complete a sentence with an adverb, instead of an object:

• Subject + Action Verb + Adverb – Gemma studies hard.

When we use linking verbs for states, senses, conditions, and other occurrences, the verb is followed by noun or adjective phrases which define the subject.

• Subject + Linking Verb + Noun Phrase – Gemma is a student.
• Subject + Linking Verb + Adjective Phrase – Gemma is very wise.

These patterns all form positive, declarative sentences. Another pattern to note is Questions, or interrogative sentences, where the first verb comes before the subject. This is done by adding an auxiliary verb (do/did) for the past simple and present simple, or moving the auxiliary verb forward if we already have one (to be for continuous tense, or to have for perfect tenses, or the modal verbs):

• Gemma studies English. –> Does Gemma study English?
• Gemma is very wise. –> Is Gemma very wise?

For more information on questions, see the section on verbs.

Finally, we can also form imperative sentences, when giving commands, which do not need a subject.

• Study English!

(Note it is also possible to form exclamatory sentences, which express heightened emotion, but these depend more on context and punctuation than grammatical components.)

Parts of Speech

General patterns offer overall structures for English sentences, while the broad grammatical units are formed of individual words and phrases. In English, we define different word types as parts of speech. Exactly how many we have depends on how people break them down. Here, we’ll look at nine, each of which is explained below. Either keep reading or click on the word types to go to the sections about their word order rules.

• Nouns – naming words that define someone or something, e.g. car, woman, cat
• Pronouns – words we use in place of nouns, e.g. he, she, it
• Verbs – doing or being words, describing an action, state or experience e.g. run, talk, be
• Adjectives – words that describe nouns or pronouns, e.g. cheerful, smelly, loud
• Adverbs – words that describe verbs, adjectives, other adverbs, sentences themselves – anything other nouns and pronouns, basically, e.g. quickly, curiously, weirdly
• Determiners – words that tell us about a noun’s quantity or if it’s specific, e.g. a, the, many
• Prepositions – words that show noun or noun phrase positions and relationships, e.g. above, behind, in, on
• Conjunctions – words that connect words, phrases or clauses e.g. and, but
• Interjections – words that express a single emotion, e.g. Hey! Ah! Oof!

Noun Phrases, Determiners and Adjectives

Subjects and objects are likely to be nouns or noun phrases, describing things. So sentences usually to start with a noun phrase followed by a verb.

• Nina ate.

However, a noun phrase may be formed of more than word.

We define nouns with determiners. These always come first in a noun phrase. They can be articles (a/an/the – telling us if the noun is specific or not), or can refer to quantities (e.g. some, much, many):

• a dog (one of many)
• the dog in the park
• many dogs

After determiners, we use adjectives to add description to the noun:

• The fluffy dog.

You can have multiple adjectives in a phrase, with orders of their own. You can check out my other article for a full analysis of adjective word order, considering type, material, size and other qualities – but a starting rule is that less definite adjectives go first – more specific qualities go last. Lead with things that are more opinion-based, finish with factual elements:

• It is a beautiful wooden chair. (opinion before fact.)

We can also form compound nouns, where more than one noun is used, e.g. “cat food”, “exam paper”. The earlier nouns describe the final noun: “cat food” is a type of food, for cats; an “exam paper” is a specific paper. With compound nouns you have a core noun (the last noun), what the thing is, and any nouns before it describe what type. So – description first, the actual thing last.

Finally, noun phrases may also include conjunctions joining lists of adjectives or nouns. These usually come between the last two items in a list, either between two nouns or noun phrases, or between the last two adjectives in a list:

• Julia and Lenny laughed all day.
• a long, quick and dangerous snake

Pronouns

We use pronouns in the place of nouns or noun phrases. For the most part, these fit into sentences the same way as nouns, in subject or object positions, but don’t form phrases, as they replace a whole noun phrase – so don’t use describing words or determiners with pronouns.

Pronouns suggest we already know what is being discussed. Their positions are the same as nouns, except with phrasal verbs, where pronouns often have fixed positions, between a verb and a particle (see below).

Verbs

Verb phrases should directly follow the subject, so in terms of parts of speech a verb should follow a noun phrase, without connecting words.

As with nouns and noun phrases, multiple words may make up the verb component. Verb phrases depend on your tenses, which follow particular forms – e.g. simple, continuous, perfect and perfect continuous. The specifics of verb phrases are covered elsewhere, for example the full verb forms for the tenses are available in The English Tenses Practical Grammar Guide. But in terms of structure, with standard, declarative clauses the ordering of verb phrases should not change from their typical tense forms. Other parts of speech do not interrupt verb phrases, except for adverbs.

The times that verb phrases do change their structure are for Questions and Negatives.

With Yes/No Questions, the first verb of a verb phrase comes before the subject.

• Neil is running. –> Is Neil running?

This requires an auxiliary verb – a verb that creates a grammatical function. Many tenses already have an auxiliary verb – to be in continuous tenses (“is running”), or to have in perfect tenses (have done). For these, to make a question we move that auxiliary in front of the subject. With the past and present simple tenses, for questions, we add do or did, and put that before the subject.

• Neil ran. –> Did Neil run?

We can also have questions that use question words, asking for information (who, what, when, where, why, which, how), which can include noun phrases. For these, the question word and any noun phrases it includes comes before the verb.

• Where did Neil Run?
• At what time of day did Neil Run?

To form negative statements, we add not after the first verb, if there is already an auxiliary, or if there is not auxiliary we add do not or did not first.

• Neil is running. –> Neil is not
• Neil ran. Neil did not

The not stays behind the subject with negative questions, unless we use contractions, where not is combined with the verb and shares its position.

• Is Neil not running?
• Did Neil not run?
• Didn’t Neil run?

Phrasal Verbs

Phrasal verbs are multi-word verbs, often with very specific meanings. They include at least a verb and a particle, which usually looks like a preposition but functions as part of the verb, e.g. “turn up“, “keep on“, “pass up“.

You can keep phrasal verb phrases all together, as with other verb phrases, but they are more flexible, as you can also move the particle after an object.

• Turn up the radio. / Turn the radio up.

This doesn’t affect the meaning, and there’s no real right or wrong here – except with pronouns. When using pronouns, the particle mostly comes after the object:

• Turn it up. NOT Turn up it.

Adverbs

Adverbs and adverbial phrases are really tricky in English word order because they can describe anything other than nouns. Their positions can be flexible and they appear in unexpected places. You might find them in the middle of verb phrases – or almost anywhere else in a sentence.

There are many different types of adverbs, with different purposes, which are usually broken down into degree, manner, frequency, place and time (and sometimes a few others). They may be single words or phrases. Adverbs and adverb phrases can be found either at the start of a clause, the end of a clause, or in a middle position, either directly before or after the word they modify.

• Graciously, Claire accepted the award for best student. (beginning position)
• Claire graciously accepted the award for best student. (middle position)
• Claire accepted the award for best student graciously. (end position)

Not all adverbs can go in all positions. This depends on which type they are, or specific adverb rules. One general tip, however, is that time, as with the general sentence patterns, should usually come last in a clause, or at the very front if moved for emphasis.

With verb phrases, adverbs often either follow the whole phrase or come before or after the first verb in a phrase (there are regional variations here). 

For multiple adverbs, there can be a hierarchy in a similar way to adjectives, but you shouldn’t often use many adverbs together.

The largest section of the Word Order book discusses adverbs, with exercises.

Prepositions

Prepositions are words that, generally, demonstrate relationships between noun phrases (e.g. by, on, above). They mostly come before a noun phrase, hence the name pre-position, and tend to stick with the noun phrase they describe, so move with the phrase.

• They found him [in the cupboard].
• [In the cupboard,] they found him.

In standard sentence structure, prepositional phrases often follow verbs or other noun phrases, but they may also be used for defining information within a noun phrases itself:

• [The dog in sunglasses] is drinking water.

Conjunctions

Conjunctions connect lists in noun phrases (see nouns) or connect clauses, meaning they are found between complete clauses. They can also come at the start of a sentence that begins with a subordinate clause, when clauses are rearranged (see below), but that’s beyond the standard word order we’re discussing here. There’s more information about this in the article on different sentence types.

As conjunctions connect clauses, they come outside our sentence and word type patterns – if we have two clauses following subject-verb-object, the conjunction comes between them:

Interjections

These are words used to show an emotion, usually something surprising or alarming, often as an interruption – so they can come anywhere! They don’t normally connect to other words, as they are either used to get attention or to cut off another thought.

• Hey! Do you want to go swimming?
• OH NO! I forgot my homework.

Clauses and Simple, Compound and Complex Sentences

While a phrase is any group of words that forms a single grammatical unit, a clause is when a group of words form a complete grammatical idea. This is possible when we follow the patterns at the start of this article, for example when we combine a subject and verb (or noun phrase and verb phrase).

A single clause can follow any of the patterns we’ve already discussed, using varieties of the word types covered; it can be as simple a two-word subject-verb combo, or it may include as many elements as you can think of:

• Eric sat.
• The boy spilt blue paint on Harriet in the classroom this morning.

As long as we have one main verb and one main subject, these are still single clauses. Complete with punctuation, such as a capital letter and full stop, and we have a complete sentence, a simple sentence. When we combine two or more clauses, we form compound or complex sentences, depending on the clauses relationships to each other. Each type is discussed below.

Simple Sentences

A sentence with one independent clause is what we call a simple sentence; it presents a single grammatically complete action, event or idea. But as we’ve seen, just because the sentence structure is called simple it does not mean the tenses, subjects or additional information are simple. It’s the presence of one main verb (or verb phrase) that keeps it simple.

Our additional information can include any number of objects, prepositional phrases and adverbials; and that subject and verb can be made up of long noun and verb phrases.

Compound Sentences

We use conjunctions to bring two or more clauses together to create a compound sentence. The clauses use the same basic order rules; just treat the conjunction as a new starting point. So after one block of subject-verb-object, we have a conjunction, then the next clause will use the same pattern, subject-verb-object.

• [Gemma worked hard] and [Paul copied her].

See conjunctions for another example.

A series of independent clauses can be put together this way, following the expected patterns, joined by conjunctions.

Compound sentences use co-ordinating conjunctions, such as and, but, for, yet, so, nor, and or, and do not connect the clauses in a dependent way. That means each clause makes sense on its own – if we removed the conjunction and created separate sentences, the overall meaning would remain the same.

With more than two clauses, you do not have to include conjunctions between each one, e.g. in a sequence of events:

• I walked into town, I visited the book shop and I bought a new textbook.

And when you have the same subject in multiple clauses, you don’t necessarily need to repeat it. This is worth noting, because you might see clauses with no immediate subject:

• [I walked into town], [visited the book shop] and [bought a new textbook].

Here, with “visited the book shop” and “bought a new textbook” we understand that the same subject applies, “I”. Similarly, when verb tenses are repeated, using the same auxiliary verb, you don’t have to repeat the auxiliary for every clause.

What about ordering the clauses? Independent clauses in compound sentences are often ordered according to time, when showing a listed sequence of actions (as in the example above), or they may be ordered to show cause and effect. When the timing is not important and we’re not showing cause and effect, the clauses of compound sentences can be moved around the conjunction flexibly. (Note: any shared elements such as the subject or auxiliary stay at the front.)

• Billy [owned a motorbike] and [liked to cook pasta].
• Billy [liked to cook pasta] and [owned a motorbike].

Complex Sentences

As well as independent clauses, we can have dependent clauses, which do not make complete sense on their own, and should be connected to an independent clause. While independent clauses can be formed of two words, the subject and verb, dependent clauses have an extra word that makes them incomplete – either a subordinating conjunction (e.g. because, when, since, if, after and although), or a relative pronoun, (e.g. that, who and which). 

• Jim slept.
• While Jim slept,

Subordinating conjunctions and relative pronouns create, respectively, a subordinate clause or a relative clause, and both indicate the clause is dependent on more information to form a complete grammatical idea, to be provided by an independent clause:

• While Jim slept, the clowns surrounded his house.

In terms of structure, the order of dependent clauses doesn’t change from the patterns discussed before – the word that comes at the front makes all the difference. We typically connect independent clauses and dependent clauses in a similar way to compound sentences, with one full clause following another, though we can reverse the order for emphasis, or to present a more logical order.

• Although she liked the movie, she was frustrated by the journey home.

(Note: when a dependent clause is placed at the beginning of a sentence, we use a comma, instead of another conjunction, to connect it to the next clause.)

Relative clauses, those using relative pronouns (such as who, that or which), can also come in different positions, as they often add defining information to a noun or take the place of a noun phrase itself.

• The woman who stole all the cheese was never seen again.
• Whoever stole all the cheese is going to be caught one day.

In this example, the relative clause could be treated, in terms of position, in the same way as a noun phrase, taking the place of an object or the subject:

• We will catch whoever stole the cheese.
