Discharges drunk men at sea (8)
I believe the answer is:
emanates
'discharges' is the definition.
The definition and answer can be both related to bodily activities as well as being verbs in their -s form.
Perhaps you can see an association between them that I don't see?
'drunk men at sea' is the wordplay.
'drunk' is an anagram indicator.
'men'+'at'+'sea'='menatsea'
'menatsea' with letters rearranged gives 'EMANATES'.
Can you help me to learn more?
(Other definitions for emanates that I've seen before include "Issues from manatees" , "Proceeds from Ena's mate, oddly" , "emerges" , "Proceeds or issues forth from a source" , "Comes forth" .)
