Form in which many twigs can be handled (5)
I believe the answer is:
besom
'form in' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'many twigs can be handled' is the wordplay.
I cannot really see how this works, but
'many' could be 'm' and 'm' is found within the answer.
'be' is found in the answer.
The remaining letters 'so' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'which' is the link.
Can you help me to learn more?
(Other definitions for besom that I've seen before include "Sweeping item" , "Twig-broom" , "Broom made from twigs tied to a handle" , "Lazy woman" , "I sweep" .)
