Feline going to church to get some poor mouse? (5)
I believe the answer is:
catch
'get some poor mouse?' is the definition.
'catch' can be an answer for 'get' (synonyms). I am not certain of the 'some poor mouse?' bit.
'feline going to church' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'going to' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'cat'+'ch'='CATCH'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for catch that I've seen before include "Intercept and hold" , "(To) snare, net" , "Disadvantage that's hidden" , "Take hold of" , "potential partner?" .)
