Song by drunk affording no escape (8)
I believe the answer is:
airtight
'affording no escape' is the definition.
I can't tell whether this defines the answer.
'song by drunk' is the wordplay.
'song' becomes 'air' (I've seen this in another clue).
'by' says to put letters next to each other.
'drunk' becomes 'tight' (slang term).
'air'+'tight'='AIRTIGHT'
Can you help me to learn more?
(Other definitions for airtight that I've seen before include "(Of a defence) having no weaknesses" , "With no opening" , "not letting out a breath?" , "Not allowing gas to pass" , "Firmly closed" .)
