Suitable, appropriate (8)
I believe the answer is:
apposite
This clue is a double definition.
'suitable' is the first definition.
(apposite means suitable or appropriate)
'appropriate' is the second definition.
(synonyms)
(Other definitions for apposite that I've seen before include "Suitable, relevant" , "fitting" , "Appropriate for purpose or occasion" , "Meet" , "Of a remark, appropriate for the occasion (8)" .)
