Swimming in baths or holding this at the bar perhaps (7)
I believe the answer is:
absinth
'holding this at the bar perhaps' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'swimming in baths' is the wordplay.
'swimming' is an anagram indicator.
'in'+'baths'='inbaths'
'inbaths' anagrammed gives 'ABSINTH'.
'or' is the link.
Can you help me to learn more?
(Other definitions for absinth that I've seen before include "sort of liqueur" , "(Originally) a wormwood-based liqueur" , "Strong liqueur with wormwood and anise" , "Shrubby plant" , "Aniseed-flavoured liqueur" .)
