Have hospital completely housed in extremely tasteless civic buildings (4,5)
I believe the answer is:
town halls
'civic buildings' is the definition.
'town halls' can be an answer for 'buildings' (town hall is a kind of building). I'm not sure about the 'civic' bit.
'have hospital completely housed in extremely tasteless' is the wordplay.
'have' becomes 'own' (to have something is to own it).
'hospital' becomes 'H' (abbreviation for hospital).
'completely' becomes 'all' (synonyms).
'housed in' is an insertion indicator.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'tasteless' with its middle taken out is 'ts'.
'own'+'h'+'all'='ownhall'
'ownhall' going into 'ts' is 'TOWN HALLS'.
Can you help me to learn more?
