What is has in german?
Haben = to have
Er hat = he has
Which form you use of 'Haben' depends on who the subject is (I/you/he/etc)
If I've understood your question correctly: "hat".
Are you indeed asking what the translation for the third person singular conjugation for the English verb "to have" into German is?
Ich habe = I have. Wir haben = We have. Sie haben = They have. Ihr habt = You (plural) have. (informal) Du hast = You (not plural) have (informal). Sie haben = You (not plural/plural) have (Formal). There you have it.
