Re-equip an army corps with a weapon (5)
I believe the answer is:
rearm
're-equip' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'an army corps with a weapon' is the wordplay.
'an army corps' becomes 'RE' (Royal Engineers).
'with' says to put letters next to each other.
'a weapon' becomes 'arm' ('arm' can be a synonym of 'weapon').
're'+'arm'='REARM'
Can you help me to learn more?
(Other definitions for rearm that I've seen before include "Take weapons again" , "Resupply with weapons" , "Strengthen one's defences" , "prepare to fight again" , "Hand new weapons" .)
