Questions & Answers about ¿Quién es tu amiga en la escuela?

Why does ¿Quién have an accent mark?

The accent mark in quién shows that it is an interrogative word (used in questions or exclamations).

• Quién (with accent) = who? in direct or indirect questions:
  
  • ¿Quién es tu amiga? – Who is your (female) friend?
• Quien (without accent) is a relative pronoun meaning who / whoever in non-question contexts:
  
  • La chica, quien es mi amiga, va a la escuela. – The girl, who is my friend, goes to school.

In questions like this one, you must use ¿Quién with an accent.

Why is there an upside-down question mark ¿ at the beginning?

In Spanish, all questions are marked with two question marks:

• An inverted question mark at the beginning: ¿
• A normal question mark at the end: ?

So the pattern is: ¿ + question + ?

Example:

• ¿Quién es tu amiga en la escuela?
  Not: Quién es tu amiga en la escuela?

This helps readers know from the very beginning that the sentence is a question.
