Equal rises to Charlie and Inch (5)
I believe the answer is:
creep
'inch' is the definition.
(I've seen this before)
'equal rises to charlie' is the wordplay.
'equal' becomes 'peer' (synonyms).
'rises' says the letters should be written backwards.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'peer' in reverse letter order is 'reep'.
'reep' put after 'c' is 'CREEP'.
'and' acts as a link.
(Other definitions for creep that I've seen before include "Advance slowly and stealthily" , "grovel" , "Move with stealth" , "Obsequious person" , "Move stealthily or along the ground" .)
