Is Mr. López in the office?

/kah-bah-YEH-roh//ka.βaˈʎe.ɾo/

Excuse me, sir, do you know where the restroom is?

Masculine Noun

Since this word ends in '-o', it is always masculine, referring only to men. The female equivalent is 'dama' (lady).

Using 'caballero' too informally

Mistake:Using 'caballero' with a friend in casual conversation.

Correction: This word is polite, use 'amigo' (friend) or just their name in informal settings.

don

/don//don/

NounA2Formal/Respectful
Use 'don' before a man's first name, typically for older or respected men, showing a high degree of deference.
A portrait of a distinguished, older gentleman with a kind expression, symbolizing a traditional title of respect and formality.

Examples

Good morning, Don Carlos.

Mi abuelo, don José, era un hombre muy sabio.

My grandfather, Don José, was a very wise man.

Le presento a don Miguel, el director de la empresa.

I'd like to introduce you to Don Miguel, the company director.

How to Use 'Don'

Always use 'don' right before a man's first name, like 'don Alberto'. Never use it with just the last name. For the last name, you would use 'señor', like 'señor García'.

Using 'Don' with a Last Name

Mistake:Hola, don Martínez.

Correction: Hola, don Carlos. OR Hola, señor Martínez. Remember, 'don' goes with the first name, and 'señor' goes with the last name.

monsieur

/mon-siúr//monˈsjeɾ/

NounB2Formal (French context)
Use 'monsieur' when referring to or directly addressing a French man, or in very specific literary contexts when quoting French.
A high quality storybook illustration of a distinguished adult man wearing a formal black suit, a white shirt, and a bow tie, standing politely.

Examples

El famoso 'monsieur' de la novela llegó tarde a la cita.

The famous 'Mr.' from the novel arrived late for the appointment.

Disculpe, monsieur, ¿sabe dónde está la embajada?

Excuse me, sir (French), do you know where the embassy is?

Se comporta como un verdadero monsieur, siempre con guantes y sombrero.

He behaves like a true gentleman (French style), always with gloves and a hat.

A Borrowed Word

Since 'monsieur' is a direct borrowing from French, it doesn't change its form in Spanish (it's invariable). You only use 'el' or 'un' before it.

Using it as a Standard Title

Mistake:Using 'monsieur' instead of 'señor' when addressing a Spanish speaker.

Correction: Only use 'monsieur' when referring specifically to a French person or in a literary context. Use 'Señor' for everyone else.

Señor vs. Caballero

The most common confusion is between 'señor' and 'caballero'. While both are polite, 'señor' is more versatile and can be used with or without a last name. 'Caballero' is specifically for directly addressing an unknown man, like 'gentleman'.
