What might be deep trouble on the way? (7)

Ross

I believe the answer is:

pothole

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

'what might be deep' is the definition.
I can't judge whether this defines the answer.

'trouble on the way?' is the wordplay.
'trouble' becomes 'hole' (hole can mean a difficult situation).
'on' is a charade indicator (letters next to each other).
'the way?' becomes 'pot' (I am not sure about this - if you are sure you should believe this answer much more).
'hole' after 'pot' is 'POTHOLE'.

Can you help me to learn more?

(Other definitions for pothole that I've seen before include "One may descend into it" , "depression on the way!" , "that can be problem when driving" , "Hollow in road" , "Deep water-made cave, pit in road" .)
