Struggle for breath, death intervening for one hanging by the neck (7)
I believe the answer is:
pendant
'one hanging by the neck' is the definition.
(a pendant is worn around the neck)
'struggle for breath death intervening' is the wordplay.
I cannot quite understand how this works, but
'death' could be 'end' (synonyms) and 'end' is found within the answer.
'struggle for breath' could be 'pant' (to pant is to struggle for breath) and 'pant' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for pendant that I've seen before include "Hanging light" , "Ornament hanging from a piece of jewellery" , "Ornament hanging from necklace" , "item suspended" , "Panted after learned one" .)
