He's up to it, by all accounts (4)
I believe the answer is:
abel
'he's' is the definition.
'up to it by all accounts' is the wordplay.
I cannot quite understand how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
The remaining letters 'abl' 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 abel that I've seen before include "The first known murder victim" , "First person killed" , "Old Testament brother" , "character in the Bible" , "Biblical murder victim" .)
