Subject Verb agreement

[CHANDEEP_SODHI]

Hi Instructors can you please tell me in this sentence what is "Daily"
as in , is it Adverb , adjective or Noun ?

Daily use of vitamins and moisturizer help your skin replenish itself .

Also i would like to know is "vitamins and moisturizer" subject of this sentence . If Yes , how come subject of a sentence is in prepositional phrase ie "of vitamins and moisturizer".

Is the below sentence correct?
Daily use of vitamins and moisturizer helps your skin replenish itself .

Also i would like to know is the form "to + Verb " always an Infinitive?

"daily" is an adjective because it modifies the subject, "use". the original sentence is incorrect because we must use the word "helps" rather than "help" to make the subject and verb agree..

"to+[verb]" is pretty much always going to be an infinitive. i'm sure you could construct some crazy exception, and i'm sure Ron will find one for us, :) but you can go with this as a general rule..
