Canonisation isn't occasion to get into kinky stuff (8)
I believe the answer is:
saintdom
'kinky stuff' is the definition.
The definition suggests a singular noun which matches the answer.
'canonisation isn't occasion to get' is the wordplay.
'canonisation' becomes 'sm' (I can't justify this - if you can you should give a lot more credence to this answer).
'isn't' becomes 'aint' (non-standard version of 'isn't').
'occasion' becomes 'do' (do is a kind of occasion).
'to get' means one lot of letters goes inside another.
'aint'+'do'='aintdo'
'sm' going around 'aintdo' is 'SAINTDOM'.
'into' is the link.
Can you help me to learn more?
(Other definitions for saintdom that I've seen before include "Perfect condition" , "Lofty station" , "attained by my aunt, perhaps" , "Great holiness" , "Canonised persons collectively" .)
