Everyday embargo on health centre (5)
I believe the answer is:
banal
'everyday' is the definition.
(I've seen this in another clue)
'embargo on health centre' is the wordplay.
'embargo' becomes 'ban' (I've seen this in other clues).
'on' is a charade indicator (letters next to each other).
'centre' says to take the centre.
The middle letters of 'health' are 'al'.
'ban'+'al'='BANAL'
(Other definitions for banal that I've seen before include "Obvious and boring" , "boringly dull" , "Boring or trivial" , "Uninspiring" , "flat" .)
