Pea soup carried by hand to primitive human (6)
I believe the answer is:
apeman
'primitive human' is the definition.
The definition suggests a singular noun which matches the answer.
'pea soup carried by hand' is the wordplay.
'soup' indicates anagramming the letters.
'carried' is a charade indicator (letters next to each other).
'by hand' becomes 'man' (both can mean a worker. I am not sure about the 'by' bit.).
'pea' with letters rearranged gives 'ape'.
'ape'+'man'='APEMAN'
'to' is the link.
Can you help me to learn more?
(Other definitions for apeman that I've seen before include "song by 4 [THE KINKS]" , "One of our extinct ancestors?" , "Tarzan, for example" , "Neanderthal type?" , "Missing link, possibly" .)
