Explanation by: Chandani

Add "a" before "few"

Using "a few" instead of "few" in a sentence changes a sentence's meaning. Whereas "a few" implies a small number of some that is greater than two, "few" implies only a small number. Other words, like "very" or "quite," may also come before "a few" or "few" and further change sentence meaning. Examples can be found below.
