Not a hand unencumbered to take the weapon (9)
I believe the answer is:
freelance
'not a hand' is the definition.
I can't tell whether this definition defines the answer.
'unencumbered to take the weapon' is the wordplay.
'unencumbered' becomes 'free' (I've seen this in another clue).
'to take' is a charade indicator (letters next to each other).
'the weapon' becomes 'lance' (lance is a kind of weapon).
'free'+'lance'='FREELANCE'
Can you help me to learn more?
(Other definitions for freelance that I've seen before include "without regular work?" , "Writer or artist who sells services to different employers" , "Independent" , "Self-employed person offering services where needed" , "Not tied to employer" .)
