However, the term "Ɔhemmaa" is often used for the queen mother, the senior queen in a matrilineal society. You could use it for a queen in a general sense, but it wouldn't be as specific.
Here are some other options, depending on the context:
* Ɔhemaa: This means "queen" in a more general sense, but could also refer to the queen of a particular area or tribe.
* Ahenemma: This is a less common term, but it also means "queen".
Ultimately, the best way to say "queen" in Twi would depend on the specific situation and who you're talking about.
