Told off, Charlie kept out of sight (4)
I believe the answer is:
chid
'told off' is the definition.
(I've seen this before)
'charlie kept out of sight' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'kept out of sight' becomes 'hid' (I've seen this before).
'c'+'hid'='CHID'
(Other definitions for chid that I've seen before include "rebuked" , "Rated" , "Lectured" , "told off" .)
