Recall inadequate qualification male coach concealed (9)
I believe the answer is:
submerged
'concealed' is the definition.
(thesaurus)
'recall inadequate qualification male coach' is the wordplay.
'recall' shows that the letters should be reversed in order.
'inadequate' means to remove the last letter (an incomplete or inadequate form of the word).
'qualification' becomes 'degree' (university qualification).
'male' becomes 'm' (common abbreviation).
'coach' becomes 'bus' (synonyms).
'degree' with its final letter taken away is 'degre'.
'degre'+'m'+'bus'='degrembus'
'degrembus' in reverse letter order is 'SUBMERGED'.
(Other definitions for submerged that I've seen before include "Completely covered by liquid" , "Under water" , "overwhelmed" .)
