Distinctive means having a special quality that makes something easy to recognize or different from everything else. When something is distinctive, it stands out in a way you can't miss.

Your best friend might have a distinctive laugh that you'd recognize across a crowded cafeteria.

The word suggests a memorable feature that becomes something's signature. Something distinctive has a quality that defines its identity. A teacher might have a distinctive way of starting class with a particular phrase. A restaurant might be known for its distinctive spicy sauce that no other place makes quite the same way.

Notice that distinctive usually describes positive or neutral qualities, not flaws. We talk about someone's distinctive voice or distinctive style.

Being distinctive means having an identity that others remember and can't easily confuse with anything else.
