Here's a breakdown:
* Hetero- comes from the Greek word "heteros" meaning "other" or "different."
* Sexual refers to the aspect of attraction related to romantic and physical intimacy.
So, a heterosexual person is attracted to someone who is different from them in terms of gender. For example, a heterosexual man would be attracted to women, and a heterosexual woman would be attracted to men.
It's important to remember that sexual orientation is a complex and personal aspect of a person's identity, and how someone identifies can be fluid and change over time.
