One has two hands raised (5,5)
I believe the answer is:
clock tower
'one' is the definition.
I know nothing about this answer so I can't tell whether this works.
'two hands raised' is the wordplay.
I cannot really understand how this works, but
an anagram of 'two' is 'tow' which is located in the answer.
The remaining letters 'clocker' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'has' is the link.
Can you help me to learn more?
(Other definitions for clock tower that I've seen before include "will it hold up the enemy's progress?" , "one looked up to for a time?" , "Big Ben, for example" .)
