So tin pot might be fashioned into receptacle (8)
I believe the answer is:
spittoon
'receptacle' is the definition.
(I know that spittoon is a type of receptacle)
'so tin pot might be' is the wordplay.
'might be' is an anagram indicator.
'so'+'tin'+'pot'='sotinpot'
'sotinpot' anagrammed gives 'SPITTOON'.
'fashioned into' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for spittoon that I've seen before include "One to aim at" , "Into pots? (Anag)" , "I may collect rejected wine" , "Old vessel for expectoration" , "old-fashioned receptacle" .)
