Formal:
* Adwuma yɛ (This is the most literal translation and means "work is")
* Adwuma wɔ hɔ (This means "there is work" and is more formal than "adwuma yɛ")
Informal:
* Adwuma wɔ (This means "there is work" and is a more informal version of the previous phrase)
* Adwuma yɛ bi (This means "there is some work" and is a more casual way to say "is work")
In addition to these, you can also use the verb "yɛ" ("to do") with a noun that refers to the specific work being done. For example:
* Mɛyɛ adwuma (I will do work)
* Ɔreyɛ adwuma (He/She is doing work)
* Wɔreyɛ adwuma (They are doing work)
The choice of which phrase to use will depend on the context and the desired level of formality.
