Feline caught with hotel fish (5)
I believe the answer is:
catch
'fish' is the definition.
(I know that fish is a more specific form of the action catch)
'feline caught with hotel' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'caught' becomes 'c' (cricket abbreviation).
'with' means one lot of letters go next to another.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'cat'+'c'+'h'='CATCH'
(Other definitions for catch that I've seen before include "Getting round" , "problem being concealed" , "Good match" , "fellow hooked for matrimony?" , "Understand" .)
