I believe the answer is:

hated

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

'loathed' is the definition.
(I've seen this before)

'laugh at edward' is the wordplay.
'HATED' is hidden within the letters.
But, I am uncertain how the hidden word is indicated.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for hated that I've seen before include "Despised" , "gave stinking review to?" , "couldn't stand" , "Seriously disliked" , "Death (anag)" .)

I've seen this clue in The Mirror.
