coexistir

To coexist — for two or more things, groups, or ideas to exist side by side, often despite differences: culturas que coexisten pacíficamente. Common in everyday, political, and academic Spanish alike.

• Las dos comunidades coexisten pacíficamente desde hace décadas. — The two communities have coexisted peacefully for decades.
• Es difícil que coexistan opiniones tan opuestas sin conflicto. — It's hard for such opposing opinions to coexist without conflict.
• Varias especies coexisten en ese mismo ecosistema. — Several species coexist in that same ecosystem.

Coexistir already implies both parties are equally present — don't pair it with dominar or superar in the same clause, since coexisting is explicitly not about one side winning out.

Often confused with convivir.
