A negative sentence is a sentence where you say “no” or “not”. The word for “no” is இல்லை.
To make a simple sentence negative (reverse the meaning), add இல்லை to the end of the sentence
Ex:
To turn a sentence into a question, add -ஆ to the end of the sentence.
Ex:
அவர் காவல்காரனா = “Is he a police officer?”
