Child in street with traps essentially and part of helmet (9)
I believe the answer is:
chinstrap
'part of helmet' is the definition.
I know that 'helmet' relates to this answer.
'child in street with traps essentially' is the wordplay.
'child' becomes 'ch' (abbreviation for child).
'street with' becomes 'st' (I've seen this in other clues).
'essentially' means to look at the middle letters.
The middle letters of 'traps' are 'rap'.
'ch'+'in'+'st'+'rap'='CHINSTRAP'
'and' is the link.
Can you help me to learn more?
(Other definitions for chinstrap that I've seen before include "Band" , "This secures cover for head" , "fastener" , "Bit of helmet" , "Thong to hold on helmet" .)
