The verb bicara means "to talk, to converse." (Note that the "c" in Indonesia corresponds to the "ch" sound in English.)
Verbs have derivational forms based on transitivity, intensity and strength of voice. So, for example
- berbicara is intransitive and means "to talk" in sentences like "She talks a lot."
- On the other hand, the prefix me- (often accompanied with the suffix -kan) makes membicarakan transitive, changing its meaning to "to talk" in sentences like "She is talking to Joe."
- dibicarakan is passive: "Joe got talked to."
- Pembicara means "a speaker."
- and pembicaraan means "a discussion" or "a speech."
