Successful person has squeeze on old writer (6,4)
I believe the answer is:
victor hugo
'writer' is the definition.
(Victor Hugo is an example)
'successful person has squeeze on old' is the wordplay.
'successful person' becomes 'victor' (victor is a kind of person. I am not sure about the 'successful' bit.**).
'has' is a charade indicator (letters next to each other).
'squeeze' becomes 'hug' ('hug' can be a synonym of 'squeeze').
'on' means one lot of letters go next to another.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'victor'+'hug'+'o'='VICTOR HUGO'
Can you help me to learn more?
(Other definitions for victor hugo that I've seen before include "writer" , "The Hunchback of Notre-Dame author" .)
