Limited company forced to adopt name (11)
I believe the answer is:
constrained
'limited' is the definition.
(constraining is a kind of limiting)
'company forced to adopt name' is the wordplay.
'company' becomes 'co' (abbreviation).
'forced' becomes 'strained' (synonyms).
'to adopt' is an insertion indicator (inserted letters are taken in or adopted).
'name' becomes 'n' (common abbreviation e.g. on forms).
'co'+'strained'='costrained'
'costrained' enclosing 'n' is 'CONSTRAINED'.
(Other definitions for constrained that I've seen before include "with shackles on" , "Awkward" , "Embarrassed" , "Besides (archaic)" , "Appearing forced" .)
