Be aware of the charge for a beginner (4)
I believe the answer is:
feel
'be aware of' is the definition.
'the charge for a beginner' is the wordplay.
'the charge for' becomes 'fee' (I've seen this in other clues).
'a beginner' becomes 'l'.
'fee'+'l'='FEEL'
(Other definitions for feel that I've seen before include "Fondle" , "16A [JUDGE]" , "Experience (an emotion)" , "Experience, perceive" , "Consider" .)
