I believe the answer is:

rot

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

'rubbish dumped in truro today' is the definition.
'rot' can be an answer for 'rubbish' (both can mean nonsense). I am unsure of the 'dumped in truro today' bit.

'in truro today' is the wordplay.
'in' says the answer is hidden in the clue.
'ROT' is hidden within 'truro today'.

Can you help me to learn more?

(Other definitions for rot that I've seen before include "crumble" , "Decay - nonsense" , "SECOND PART OF 25" , "Decompose; rubbish" , "Rhubarb" .)

I've seen this clue in The Sun.
