It's trendy to work around canines? (9)
I believe the answer is:
dentistry
'it's trendy to work around canines?' is the definition.
I can't judge whether this defines the answer.
'it's trendy to work around' is the wordplay.
'it's' becomes ''tis' (I've seen this before).
'to work' is an anagram indicator (letters worked into a new order).
'around' means one lot of letters goes inside another.
'trendy' anagrammed gives 'dentry'.
'tis' inserted into 'dentry' is 'DENTISTRY'.
Can you help me to learn more?
(Other definitions for dentistry that I've seen before include "Practice relating to teeth" , "It's trendy in profession of teeth-care" , "It's trendy to engage in care in teeth" , "Professional care of teeth" , "Work which is looking down in the mouth?" .)
