Question

i can't understand english (make it affirmative)

Answer 1

I understand English.

Affirmative sentences always direct some positive sentence and the opposite of affirmative sentence are negative.

Statements that shown yes or something positive is known as affirmative sentence.

In this case, the sentence is I can’t understand English and this is a purely negative sentence that implies that the person do not know English.

So if you change it to affirmative then you have to write I understand English very well.
