And the new chap I brought round is no help (8)
I believe the answer is:
handicap
'no help' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'and the new chap i brought round' is the wordplay.
'the new' indicates an anagram.
'brought round' means one lot of letters goes inside another.
'chap'+'i'='chapi'
'chapi' anagrammed gives 'hicap'.
'and' going inside 'hicap' is 'HANDICAP'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for handicap that I've seen before include "It makes progress difficult" , "Place at a disadvantage" , "Block" , "barrier" , "millstone" .)
