Correct spelling

agree

Correct spelling, explanation: agree comes from the Old French word agreer (abbreviation of a phrase a gré), hence a similar spelling of these two. Doubling g, as in aggree is a mistake and there is no reason to do that. The only correct spelling is agree.

Definition of agree:
verb, acknowledge, admit sb is right
I don’t agree with you in terms of hiring new people, I think we should organize training for old employees first.
I wanted pink walls in the bedroom but Mark didn’t agree.


Incorrect spelling

aggree

Incorrect spelling, explanation: this form is incorrect (the correct one is agree) since there is no need or historical reason to double consonant g in this word. Thus aggree is a mispelling. The correct form is agree – from French agreer (favourably).

Incorrect spelling

agre
