People correspond - by telepathy? (8)
I believe the answer is:
mentally
'people correspond by telepathy?' is the definition.
I can't judge whether this defines the answer.
'people correspond by' is the wordplay.
'people' becomes 'men' (men are people).
'correspond' becomes 'tally' (synonyms).
'by' means one lot of letters go next to another.
'men'+'tally'='MENTALLY'
Can you help me to learn more?
(Other definitions for mentally that I've seen before include "rationally" , "without pencil and paper" , "not in writing" , "in their heads" , "by way of intellect" .)
