Give weapons to some regular militia (3)
I believe the answer is:
arm
'give weapons' is the definition.
(I've seen this in other clues)
'some regular militia' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ARM' is hidden in the letters of 'regular militia'.
'to' is the link.
(Other definitions for arm that I've seen before include "Test of strength with elbows on the table" , "inlet" , "strip of land?" , "Limb; weapon" , "Limb or branch" .)
