Apartment uni loaned out with gas problems (9)
I believe the answer is:
flatulent
'out with gas problems' is the definition.
I can't tell whether this definition defines the answer.
'apartment uni loaned' is the wordplay.
'apartment' becomes 'flat' (synonyms).
'uni' becomes 'u' (U is an abbreviation for university).
'loaned' becomes 'lent' ('lend' can be a synonym of 'loan').
'flat'+'u'+'lent'='FLATULENT'
Can you help me to learn more?
(Other definitions for flatulent that I've seen before include "Suffering from wind or gas" , "Suffering from excessive intestinal gas" .)
