Do they pull tall buildings? (6)
I believe the answer is:
towers
'tall buildings?' is the definition.
(I've seen this before)
'do they pull' is the wordplay.
I cannot really see how this works, but
'pull' could be 'tow' (tow is a kind of pull) and 'tow' is located in the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
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" .)
