Is pantolonu ,incorrect?
Yes, if you say 'pantolonu lütfen', then the meaning changes slightly.
Can you explain what that would mean, please?
that would only make sense in response to something;
So it only makes sense if the sentence before had an accusative object.
yalnız bu biraz devrik bir cümle
Would the plural of, "pantolon," be, "pantolonler," or does it not become plural?
