They go round with beers; about ten in number (5)
I believe the answer is:
axles
'they go round' is the definition.
The definition suggests an adverb but the answer is not.
'beers about ten in number' is the wordplay.
'beers' becomes 'ales' (ale is a type of beer).
'about' is an insertion indicator.
'ten in number' becomes 'x' (I can't explain this - if you can you should believe this answer much more).
'ales' enclosing 'x' is 'AXLES'.
'with' is the link.
Can you help me to learn more?
(Other definitions for axles that I've seen before include "Shaft on which wheels rotate" , "Wheel shafts" , "Rods between wheels" , "Wheel rods" , "They may be involved in turning" .)
