Invited to have red construction confined (9)
I believe the answer is:
bedridden
'confined' is the definition.
(thesaurus)
'invited to have red construction' is the wordplay.
'invited' becomes 'bidden' (I've seen this in another clue).
'to have' is an insertion indicator.
'construction' is an anagram indicator (answer constructed from certain letters).
'red' anagrammed gives 'edr'.
'bidden' placed around 'edr' is 'BEDRIDDEN'.
(Other definitions for bedridden that I've seen before include "permanently retired" , "Unwell" , "laid up" .)
