Cultivate source of munitions — and do so again? (5)
I believe the answer is:
rearm
'cultivate' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'source of munitions and do so again?' is the wordplay.
'source of' suggests taking the first letters.
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'do so again?' becomes 'rear' (I can't explain this - if you can you should give a lot more credence to this answer).
The first letter of 'munitions' is 'm'.
'm' after 'rear' is 'REARM'.
Can you help me to learn more?
(Other definitions for rearm that I've seen before include "prepare to fight again" , "Provide new weaponry" , "Equip with new or better weapons" , "Increase weaponry" , "Provide with fresh weapons" .)
