Easily offended, Charlie's grabbed by unruly youth (6)
I believe the answer is:
touchy
'easily offended' is the definition.
(I've seen this in another clue)
'charlie's grabbed by unruly youth' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'grabbed by' indicates putting letters inside.
'unruly' is an anagram indicator.
'youth' anagrammed gives 'touhy'.
'c' inserted into 'touhy' is 'TOUCHY'.
(Other definitions for touchy that I've seen before include "Thin-skinned, easily offended" , "Easily offended in tactile way?" , "Oversensitive" , "Ticklish" , "Irritable" .)
