Small utensil used by son, a poet, possibly (8)
I believe the answer is:
teaspoon
'small utensil' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'son a poet possibly' is the wordplay.
'possibly' is an anagram indicator.
'son'+'a'+'poet'='sonapoet'
'sonapoet' with letters rearranged gives 'TEASPOON'.
'used by' acts as a link.
Can you help me to learn more?
(Other definitions for teaspoon that I've seen before include "With OAP onset, use it at table" , "Small piece of cutlery" , "Not Aesop (anag.)" , "It creates a stir" , "Small medicine dispensing unit" .)
