* γριά (griá): This is the most common and straightforward word for "old woman," often implying age and sometimes a bit of frailty. It can be neutral or slightly negative depending on context.
* γηραιά (gēraia): This is a more formal and respectful word for "old woman," emphasizing age and dignity.
* κυρία (kyría): While literally meaning "lady," this can be used for an older woman, especially if you want to be polite and respectful. However, it doesn't specifically indicate old age.
The best choice depends on the context. If you need a simple, everyday term, γριά (griá) is suitable. If you want to be more respectful, γηραιά (gēraia) or κυρία (kyría) would be better.
