Intellectual urge by bloke to get promotion (7)
I believe the answer is:
egghead
'intellectual' is the definition.
(I know that egghead is a type of intellectual)
'urge by bloke to get promotion' is the wordplay.
'urge' becomes 'egg' (as in egging someone on).
'by' is a charade indicator (letters next to each other).
'bloke' becomes 'he' ('he' refers to a man).
'to get' says to put letters next to each other.
'promotion' becomes 'ad' (short for advert).
'egg'+'he'+'ad'='EGGHEAD'
(Other definitions for egghead that I've seen before include "Intellectual - highbrow" , "scholar" , "where soldiers may take a dip?" , "Informal intellectual of ovoid type" , "Intellectual person" .)
