"Que tiene" in Spanish translated to "what he/she/it has/you have" "Tiene" is the he/she/it/you(formal) conjugation of the Spanish verb "tener" which means "to have", therefore "tiene" means "he, she or it has/you have" "Que" can either mean "what" or "that" "Que tiene?" as a question means "What does he/she/it/you have?" "....que tiene" in the middle of a sentence usually means "that/which he/she/it has/you have". 'tener que' = 'to be obliged/have to' 'que tiene que' = 'which/who is/are obliged//has/have to'
Él tiene means: he has. It is phrase and not a complete sentence.
