"Do you have a big bed?"
Translation:¿Tú tienes una cama grande?
Ok why isnt... tu tiene... Acceptable...doesnt seem to be any plural indications here
Two reasons. Tu means your (familiar). You (familiar) requires an accent. Tienes is the conjugation of tener for you (familiar). Without the s it means you (formal), she or he has. You (plural) & they are always tienen in the Americas. (In Spain, you, (plural familiar) have is tenéis. (Duo doesn't teach the vosotros/as form.) http://www.spanishdict.com/conjugate/tener Whenever you learn a new verb, it's helpful to learn its conjugation.
