One ordered about ten cattle (4)
I believe the answer is:
oxen
'cattle' is the definition.
(type of cattle)
'one ordered about ten' is the wordplay.
'ordered' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'ten' becomes 'X' (Roman numeral).
'one' anagrammed gives 'oen'.
'oen' going around 'x' is 'OXEN'.
(Other definitions for oxen that I've seen before include "Domesticated bovine draft animals" , "Steers" , "Bullocks" , "Domestic bovines" , "Beef stock" .)
