Do they pull tall buildings? (6)
I believe the answer is:
towers
'tall buildings?' is the definition.
(I've seen this in another clue)
'do they pull' is the wordplay.
I cannot quite understand how this works, but
'pull' could be 'tow' (to tow is to pull or drag) and 'tow' is found within the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for towers that I've seen before include "have some pull" , "Keeps" , "Tall thin structures" , "vehicles for use in breakdowns?" , "Turrets" .)
