colisión
/koliˈsjon/ · B2 · noun · f
collision
💥🚗 colisión = col- (together) + lis (strike): things striking together
Comes from Latin collisio, from collidere: com- (together) + laedere (to strike). English collide and collision share the same root, so the Spanish word is an easy match: ends in -ión like English -ion.
