Support given about engaging English poet (5)

I believe the answer is:

yeats

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

'poet' is the definition.
(Yeats is an example)

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

(Other definitions for yeats that I've seen before include "Poet William Butler or painter Jack B" , "William Butler ..., great Irish poet" , "he wrote" , "W.B. - (Irish poet)" , "Irish poet (The Winding Stair)" .)

I've seen this clue in The Telegraph.
