Discharge on electronic screen boosted (7)
I believe the answer is:
relieve
'discharge' is the definition.
(relieving is a kind of discharging)
'on electronic screen boosted' is the wordplay.
I cannot really understand how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the answer.
'electronic' could be 'e' (as in e-mail or e-books) and 'e' is located in the answer.
The remaining letters 'live' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for relieve that I've seen before include "Lighten a burden or raise a seige" , "Alleviate pain or stress" , "raise a siege" , "Take over work from someone" , "Comfort" .)
