Steer with this? Not right! (5)
I believe the answer is:
udder
This clue might be a double definition.
'steer with this?' is the first definition.
(I've seen this before)
'not right' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for udder that I've seen before include "Bovine mammary gland" , "Cow's teat" , "Mammary gland of cow" , "Milk supply" , "Animal mammary gland" .)
