What's the difference between 'señor' and 'caballero'?

The word 'señor' is the standard, everyday respectful address equivalent to 'sir' or 'Mr.,' while 'caballero' (literally 'gentleman/knight') is more elevated and formal — used primarily in high-end customer service, formal announcements, or when showing extra deference.

When do I use 'don' before someone's name?

The title 'don' is placed before a man's first name (never last name alone) as a sign of respect, particularly for older men or authority figures — it's common in Latin America when addressing elders, community leaders, or in service contexts like 'Don José, su mesa está lista.'

How do I say 'Dear Sir' in a formal letter?

A formal letter opening is 'Estimado señor:' (Dear Sir) or 'Muy señor mío:' (very much my sir, very formal/traditional), with 'Estimado señor' being the modern standard for business correspondence.

How to Say Sir in Spanish

Written by Sofia Ramirez, Lead Spanish Curriculum Editor · Reviewed May 2026

Señor · noun · seh-NYOHR

The primary translation of 'sir' is 'señor,' the universal respectful title for men in Spanish. 'Caballero' (gentleman) is a more elevated form used in very formal or customer service contexts. 'Don' is a traditional respect title placed before a man's first name (Don Carlos, Don Miguel). The abbreviation 'Sr.' is used in written correspondence.

Pronounced seh-NYOHR with stress on the second syllable. The 'ñ' produces the distinctive 'ny' sound unique to Spanish.

Disculpe, señor, ¿me puede indicar dónde queda el banco?

Excuse me, sir, can you tell me where the bank is?

Avoid These Mistakes When Using Señor

Using 'sir' as a knighthood title

Incorrect: Es el Sir Elton John.

Correct: Es Sir Elton John. (kept in English for knighthoods)

For British knighthoods, 'Sir' is kept in English as a proper title even in Spanish text. The Spanish 'señor' is not a title of nobility — it's simply a polite form of address.

Overusing 'caballero'

Incorrect: Oye, caballero, pásame la sal. (at a casual dinner)

Correct: Oye, señor / amigo, pásame la sal.

'Caballero' is very formal and mainly used in service industries or to address strangers politely. In casual settings among acquaintances, it sounds excessively formal or sarcastic.
