Cut out bodily exertion without hesitation (6)
I believe the answer is:
excise
'cut out' is the definition.
(excise can mean to cut out or remove)
'bodily exertion without hesitation' is the wordplay.
I cannot really see how this works, but
'without' could be 'ex' (Latin) and 'ex' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for excise that I've seen before include "Tax on certain goods and commodities" , "Internal tax" , "Duty; cut out" , "that wretches hatefully collect" , "A tax to be cut out, perhaps" .)
