What does it mean word for word?
The phrase is composed of several parts: quiénes is the plural form of the word for "who". son is the third-person plural form of the verb ser, which is used here to express essential identity. And ellos means "they" when referring to males or a mixed group.
Which one should you use?
While ¿Quiénes son ellos? is a complete way to ask the question, in casual Spanish, the subject pronoun ellos is often omitted. In those cases, you can simply say ¿Quiénes son? to mean "Who are they?"
How does it change in a sentence?
Because the subject being asked about is plural, you must use the plural form of who, which is quiénes. Additionally, if you were referring specifically to a group of only women, you would replace ellos with ellas.
Did you know?
- In some Spanish dialects, asking ¿Quiénes son? can be used as a way to challenge someone's authority or status rather than just asking for a name.
- In Spanish, even if a group of 'they' contains one hundred women and only one man, you must use the masculine ellos to refer to them.
- The Spanish word son shares a common linguistic ancestor with the English word 'sound'.
