What's the difference between يتكلموا and يتكلمون? thank you!
How would I know when to use each one?
Jazak allahu kharan
Also when can I use the word بلى, does it mean "yea"?
يتكلمون = present tense = They speak
يتكلموا = It will not be used alone in a sentence.
When negative prepositions like لم or لن enter in this verb يتكلمون it will become
لم يتكلموا or لن يتكلموا - The letter ن will be dropped.
لم يتكلموا = They didn't talk or They didn't speak
لن يتكلموا = Verily they didn't speak or They will never speak.
بلى means نعم = Yes.
Generally it is not familiar in speaking Arabic, although it was used in Quran.
Hope it will help you.
