...one hauling column (5)
I believe the answer is:
tower
This might be a double definition.
'one hauling' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'column' is the second definition.
(I know that column can be written as tower)
Can you help me to learn more?
(Other definitions for tower that I've seen before include "Minaret, for example" , "Campanile, spire etc" , "tugboat" , "Rise to great height" , "Wrote (anag.)" .)
