Victor, one with wise face (6)
I believe the answer is:
visage
'face' is the definition.
(I know that visage is a type of face)
'victor one with wise' is the wordplay.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'one' becomes 'i' (Roman numeral).
'with' means one lot of letters go next to another.
'wise' becomes 'sage' (similar in meaning).
'v'+'i'+'sage'='VISAGE'
(Other definitions for visage that I've seen before include "Clock" , "Face, aspect" , "A person's face, countenance" , "Mug" .)
