Possibly one contains a bit of veal (4)
I believe the answer is:
oven
'possibly one contains a bit of veal' is the definition.
I can't judge whether this definition defines the answer.
'possibly one contains a bit of veal' is the wordplay.
'possibly' is an anagram indicator.
'contains' indicates putting letters inside.
'a bit of' indicates taking the first letters.
The initial letter of 'veal' is 'v'.
'one' with letters rearranged gives 'oen'.
'oen' going around 'v' is 'OVEN'.
Can you help me to learn more?
(Other definitions for oven that I've seen before include "Enclosed chamber for cooking" , "Metal box in which to roast" , "Liquid oxygen; salmon" , "Stove" , "A hot place" .)
