Legal adviser thus permitted to accompany men (9)
I believe the answer is:
solicitor
'legal adviser' is the definition.
(I've seen this before)
'thus permitted to accompany men' is the wordplay.
'thus' becomes 'so' ('so' can be a synonym of 'thus').
'permitted' becomes 'licit' (I've seen this before).
'to accompany' says to put letters next to each other.
'men' becomes 'or' (I've seen this in other clues).
'so'+'licit'+'or'='SOLICITOR'
(Other definitions for solicitor that I've seen before include "Type of lawyer" , "Legal practitioner" , "Court player" , "Cake topping" , "Law practitioner" .)
