Questions & Answers about Qui té la culpa?
Qui means who. It is the interrogative word used to ask about a person.
So Qui té la culpa? literally starts with Who... ?
Because qui is treated as grammatically singular in this kind of question.
- qui = who
- té = has / is the one who has
So Catalan uses the 3rd person singular form:
- Qui té la culpa? = Who is to blame?
- literally: Who has the blame/fault?
Even though the answer could refer to more than one person, the question word itself takes singular agreement.
The accent in té helps distinguish it from te.
- té = has (from tenir, to have)
- te = you in some uses, or tea in some contexts depending on dialect/spelling conventions
So the accent is important because it marks a different word and also helps with pronunciation.
