Cheers: drank liquid from this! (7)
I believe the answer is:
tankard
'this' is the definition.
The definition suggests a singular noun which matches the answer.
'cheers drank liquid' is the wordplay.
'cheers' becomes 'ta' (both can informally mean thank you).
'liquid' is an anagram indicator.
'drank' anagrammed gives 'nkard'.
'ta'+'nkard'='TANKARD'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for tankard that I've seen before include "Beer-glass" , "Drinker's pot" , "One-handled beer mug" , "Mug-like drinking vessel" , "Vessel tracked" .)
