He joined what was cut (5)
I believe the answer is:
hewed
'cut' is the definition.
(I've seen this in another clue)
'he joined' is the wordplay.
'joined' becomes 'we'd' (I've seen this in another clue).
'he'+'wed'='HEWED'
'what was' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for hewed that I've seen before include "Hacked" , "Cut with blows" , "Cut, chopped" , "Axed" .)
