Might impede one being strangely numb in the middle here with the odd ache (8)
I believe the answer is:
encumber
'might impede one' is the definition.
I can't judge whether this definition defines the answer.
'strangely numb in the middle here with the odd ache' is the wordplay.
'strangely' indicates anagramming the letters.
'in the middle' indicates the central letters.
'with' means one lot of letters go next to another.
'the odd' means one should take alternating letters.
The central letters of 'here' are 'er'.
The alternate letters of 'ache' are 'ce'.
'numb'+'er'='number'
'number' put after 'ce' is 'cenumber'.
'cenumber' anagrammed gives 'ENCUMBER'.
'being' is the link.
Can you help me to learn more?
(Other definitions for encumber that I've seen before include "Restrict or impede" , "Be a burden to, hamper" , "Constrain" , "Burden with, oppress (8)" , "Be a burden to, place load on" .)
