Question

I was not doubtful it was you only

Answer 2

I was not sure whether it was you.

• The argument is that positive, or affirmative, words are spoken in a matter-of-fact tone, but negative sentences state something is false.
• In English, the most frequent approach to change a positive statement into a negative one is to add the word not.
• The word is not frequently put after a helpful verb in a declarative phrase (such as a form of do, have, or be).
• As a result, the provided statement might be expressed in the negative form as - "I was not sure whether it was you."
