‘Miedo‘ (Fear) is a great Spanish word that changes meaning completely depending on whether it is used literally or colloquially:
Ay, ¡me das mucho miedo! – Ah, you’re really scaring me! (For ‘ghosts’ at Halloween!)
Hubo una gran tormenta mientras íbamos caminando por el campo y pasamos mucho miedo – There was a big storm while we were walking in the countryside and we got really scared
Una película de miedo – A horror film
Miedo is also used colloquially here in Spain (by people of all ages) to mean something is great:
Este helado está de miedo – This ice cream is amazing
Fuimos a los Alpes este verano y lo pasamos de miedo – We went to the Alps this summer and had a fantastic time.
