Ross

I believe the answer is:

eat

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

'to do' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.

'what every poet laureate' is the wordplay.
'EAT' is hidden within the letters.
However, I'm unsure how the hidden word is indicated.

'has' acts as a link.

Can you help me to learn more?

(Other definitions for eat that I've seen before include "Devour" , "to do etching?" , "Ingest" , "tolerate in diet" , "Feed" .)
