He/She/It has to have or have to have?

[Oinas]

Which one is correct in these example clauses:"She has to have persistence" or "she have to have persistence.I guess the first one,am I right? How about these clauses:"She has to go" or "she have to go".With kind regards,Oinas.

She has to have persistence.

The verb 'have' changes to 'has' when used in the Present Simple with the pronouns 'he, she, it'..

The Germans have a great saying: "Er, sie es immer s" or "he, she, it always s"
