Steers round ten on inside bend (4)
I believe the answer is:
oxen
'steers' is the definition.
(I've seen this before)
'round ten on inside bend' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'ten' becomes 'x' (roman numeral).
'on inside bend' becomes 'en' (I am not sure about this - if you are sure you should believe this answer much more).
'o'+'x'+'en'='OXEN'
Can you help me to learn more?
(Other definitions for oxen that I've seen before include "workers in the field?" , "strong animals" , "Domesticated bovine draft animals" , "Draught animals" , "Lowers" .)
