tower over

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

'tug' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'ended to loom above' is the wordplay.
'ended' becomes 'over' (synonyms).
'to loom' becomes 'tower' (synonyms).
'above' means one lot of letters go next to another (in a down clue, some letters go above others).
'over' after 'tower' is 'TOWER OVER'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
