Horse possibly detested by Ted (5)

I believe the answer is:

steed

I'm a little stuck... Click here to teach me more about this clue!

'horse' is the definition.
(steed is a kind of horse)

I don't understand how the remainder of the clue works.

(Other definitions for steed that I've seen before include "Powerful horse" , "ride" , "Trusty horse" , "Horse, mount" , "Warhorse" .)

I've seen this clue in the Evening Standard.
