✅ Answer:
The suffix “-ma” in “konuşma” is a negation suffix that turns a verb into its negative imperative form, meaning “do not do something”.
Breakdown of the sentence:
- “Aptalca” → stupidly (adverb, describing how the action is done)
- “Konuşma” → Do not speak
🔹 “Konuş” → Speak (imperative, command form)
🔹 “Konuşma” → Do not speak (negative imperative)
For example:
✅ “Güzelce konuş.” → Speak nicely.
❌ “Güzelce konuşma.” → Do not speak nicely.
So, “-ma” is a negative imperative suffix that is used to forbid or prevent an action.
