"Hi" in Spain vs. Mexico: It's "Hola" in Both
"Hi" is English. In Spanish — spoken in both Spain and Mexico — the universal informal greeting is:
¡Hola!
Regional Nuances
| Context | Spain (Peninsular) | Mexico |
| Informal greeting | ¡Hola! / ¿Qué tal? | ¡Hola! / ¿Qué onda? / ¿Qué pasó? |
| Formal / respectful | Buenos días / Buenas tardes | Buenos días / Buenas tardes |
| Phone answer | ¿Diga? / ¿Sí? | Bueno / ¿Sí? / ¡Hola! |
| Goodbye | Adiós / Hasta luego | Adiós / Hasta luego / Nos vemos |
Pronunciation Differences
- Spain: Distinción — c/z = /θ/ (th). "Hola" = [ˈola]. "Gracias" = [ˈɡɾaθjas].
- Mexico: Seseo — c/z/s = /s/. "Hola" = [ˈola]. "Gracias" = [ˈɡɾasjas].
- Voseo (vos) absent in Mexico (uses tú); used in parts of Central America, not Mexico.
Bottom Line
Say "¡Hola!" anywhere in the Spanish-speaking world and you'll be understood. Add "Buenos días" (morning) or "Buenas tardes" (afternoon) for politeness. The word "hi" itself is not Spanish.
