Will reservists get involved in ordeal? (9)
I believe the answer is:
testament
'will' is the definition.
('testament' can be a synonym of 'will')
'reservists get involved in ordeal?' is the wordplay.
I cannot quite see how this works, but
'reservists' could be 'ta' (abbreviaton for Territorial Army) and 'ta' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for testament that I've seen before include "with 1a [NEW] where is Mark?" , "Will - covenant" , "Biblical division" , "(Person's) will" , "Tribute" .)
