In Akan, there seems to mainly be agreement in number with nouns.
Kofi mmoa akɛseɛ no awu
“Kofi's big animals have died.”
In this case, the feature plural of the noun mmoa, seems to be shared with the adjective. It is difficult to say whether the noun or the adjective is the controller, but the domain seems to be the phrase level.
Though here, akɛsie is plural, while bayerɛ does not seem to be plural, and neither does the second adjective.
na wakɔfa saa dompe no de ndompe mmienu no adwane.
“he will then grab the other bone and run away with two bones”
The adjective mmienu seems to have an inherent feature of number, and this is shared with the noun, which is also inflected for it. This could indicate that adjectives are the controllers rather than the nouns.

There seem to be two functions associated with the a-prefixes: "a-" occurs in purpose clauses and in SVCs. The derived verbs are sometimes called a-form verbs and Akan scholars do not agree on the grammatical nature of a-form verbs.
The other a-prefix has been cllassified as a perfective (PFV) verb form, but also as Aorist.
