Questions & Answers about Mimi nina mkoba mpya.
Nina is the present-tense form of the verb kuwa na (“to have”). It breaks down as:
• ni- = first-person-singular subject prefix (“I”)
• -na- = present-tense marker
• (verb root -wa is actually fused into the construction here)
So nina means “I have.”
You negate nina by replacing ni- with si- and dropping the tense marker -na-, so you get Sina mkoba mpya:
• si- = first-person negative prefix
• -na- is omitted in simple statement negation
Use the second-person prefix u- and add the question intonation or je at the start:
• Una mkoba mpya?
• Je, una mkoba mpya?
Both mean “Do you have a new bag?”
Past tense: replace ni- with li- → Nilin a mkoba mpya (more commonly Nilikuwa na mkoba mpya using kuwa na).
Future tense: use ta- → Nitakuwa na mkoba mpya (“I will have a new bag”).
