Turner has beer, drinking ten! (4)
I believe the answer is:
axle
'turner' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'beer drinking ten' is the wordplay.
'beer' becomes 'ale' (type of beer).
'drinking' indicates putting letters inside.
'ten' becomes 'X' (Roman numeral).
'ale' enclosing 'x' is 'AXLE'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for axle that I've seen before include "Rod at centre of wheel" , "Rod making wheels turn" , "need of wheeled cart?" , "wheel section" , "Pin in revolver" .)
