You’re welcome. I’d say it’s fairly flexible in that situation but it’ll depend a bit on what’s being agreed; we’d usually use a preposition overall, but it wouldn’t really cause any confusion without for something like a plan – as the article says, it’s more common without when it comes to opinions.

thank you for this explanation. I recently came across this use of agree when I was listening to the BBC. The sentence was “the UN meeting hoping to agree a global treaty on plastics pollution ends without the deal despite the last-ditch efforts overnight”. I was confused because of the absence of any preposition. Is it something stricly in formal occasions or can I just say “We need to agree a plan for the weekend trip?”. Thank you

Hi Andrew,

Yes, it is used this way sometimes, probably a form that would be worth including in the article: “agree + noun” is typically used with contracts, agreements or anything that can be negotiated really, essentially meaning to agree on a particular version of the noun.

With document comments, yes it’s generally okay to use very short note form in that way, ‘agree’ or ‘okay’ should both be fine.

There may be some flexibility depending on regional use, but generally this should be a good broad starting point.

Hi Ash, I mean that we’re discussing the general act of agreeing, without the topic mentioned – when we name the topic, it becomes specific.
So, general agreement would be: “The girls agreed with each other.” but more specific would be “The girls agreed on which cafe to go to.” I hope that clarifies it?
