One who gets a kick out of computers? (6)
I believe the answer is:
hacker
'one who' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a kick out of computers?' is the wordplay.
'a kick' becomes 'hack' (I've seen this before).
'out of computers?' becomes 'er' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hack'+'er'='HACKER'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for hacker that I've seen before include "One imposing cuts" , "Cyber-terrorist" , "Novice golfer" , "who bypasses security measures?" , "Jim -- (Yes, Minister)" .)
