Questions & Answers about ¿Tuviste problemas con tu aerolínea?
Why is the word for 'you had' tuviste instead of something like 'teniste'?
I noticed problemas ends in '-as'. Is it a feminine word?
Why is there no accent mark on tu?
Tu without an accent mark is the possessive adjective 'your' (as in tu aerolínea, your airline). If it had an accent mark (tú), it would mean the subject pronoun 'you'.
