Personally provided solver with invitation to quiz setter (2,3,3,2)

I believe the answer is:
if you ask me
'personally' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'solver with invitation to quiz setter' is the wordplay.
'solver' becomes 'you' (the person solving the crossword).
'with' says to put letters next to each other.
'invitation' becomes 'if' (I can't explain this - if you can you should believe this answer much more).
'to quiz' becomes 'ask' (quiz can mean to ask a question).
'setter' becomes 'me' (the setter of the clue).
'you' put after 'if' is 'ifyou'.
'ifyou'+'ask'+'me'='IF YOU ASK ME'
'provided' acts as a link.
Can you help me to learn more?
