I’m left in trousers with replacement bits (8)
I believe the answer is:
implants
'replacement bits' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'i'm left in trousers' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' means one lot of letters goes inside another.
'trousers' becomes 'pants' (synonyms).
'l' put into 'pants' is 'plants'.
'im'+'plants'='IMPLANTS'
'with' is the link.
Can you help me to learn more?
(Other definitions for implants that I've seen before include "grafts" , "bust up thanks to these" , "Inserts, ideas in mind or substance into living tissue" .)
