Something that is distinct is (1) easily distinguishable from other things, (2) discrete, or (3) easy to see. Something that is distinctive is an identifying or unique feature of something else—for example, the distinctive leaves of the oak tree, or the distinctive voice of Bob Dylan. This is the traditional definition of distinctive, anyway. It is often used in place of distinct, especially in the latter’s first sense.
