What Does Quien Mean in Spanish? Simple Guide (2026)

Quien (pronounced kee-en) is a Spanish word that translates to “who” in English. It is primarily used as a relative or interrogative pronoun to refer to people, asking about identity or specifying individuals in a sentence.

Spanish learners often encounter quien early on because it is essential for asking questions and forming complex sentences. But there’s more to quien than just “who.” Let’s dive into its meaning, usage and nuances.

Origin and Popularity of “Quien”

The word quien originates from Latin “quem”, the accusative form of qui, meaning “who.” Over centuries, it evolved into the modern Spanish quien, keeping its core function as a pronoun that identifies people.

Today, quien is widely used in Spanish-speaking countries across Latin America, Spain, and communities worldwide. Its popularity stems from its versatility:

• Questions: Asking about identity (¿Quién eres? – Who are you?)
  
• Relative clauses: Referring to someone previously mentioned (El hombre, quien llegó tarde, pidió disculpas. – The man, who arrived late, apologized.)
  
• Formal writing: Often seen in literature and professional Spanish.

Pronunciation Tips 🗣️

How to Use “Quien” Correctly

A. As an Interrogative Pronoun

When asking about a person, quien is used in questions:

• Singular:
  
  • ¿Quién llamó por teléfono? → Who called on the phone?
    
• Plural (formal in Spain or literary):
  
  • ¿Quiénes son tus amigos? → Who are your friends?
    

Tips:

• Always include the accent on quién in questions; without it, the meaning changes.
  
• When addressing someone casually, you can combine it with es or son depending on singular/plural.
  

B. As a Relative Pronoun

Quien can also link clauses, like “who” in English:

• El niño, quien ganó el premio, está feliz. → The boy, who won the prize, is happy.
  
• Note: In formal writing, commas often surround the relative clause, but in casual speech, the commas may be omitted.
  

Important nuance:

• Quien usually refers to people, not objects or animals (use que for that).

2. Using quien for things instead of people:
   
   • ❌ El libro, quien es interesante…
     
   • ✅ El libro, que es interesante…
     
3. Plural confusion:
   
   • Quiénes is the plural form when asking about multiple people:
     
     • ¿Quiénes asistirán a la reunión? → Who will attend the meeting?
