Jumble sale incuding ten vehicle parts (5)
I believe the answer is:
axles
'vehicle parts' is the definition.
'jumble sale incuding ten' is the wordplay.
I cannot really understand how this works, but
'ten' could be 'x' (Roman numeral) and 'x' is found in the answer.
an anagram of 'sale' is 'ales' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for axles that I've seen before include "Shafts of wheels" , "Wheel shafts" , "Rods between wheels" , "Shaft on which wheels rotate" , "Wheel rods" .)
