I just want to reiterate that I can be available next week if so required.
I reiterated the fact that we had no milk. It means resay something. :)
Has and have are two forms of the infinitive to have Has is used for he, she and it, and generally speaking third person singular. (eg Richard has a lot of friends) Have is used for all other case...
Has is used in the present: Tom has a soccer tournament today. Had is for the past: Lauren had an ice cream cone three hours ago.
