Get away from electronic gadget? Well, once! (4)
I believe the answer is:
egad
'get away from electronic gadget? well once' is the definition.
I can't judge whether this defines the answer.
'get away from electronic gadget?' is the wordplay.
'away from' is a deletion indicator.
'electronic' becomes 'e' (as in e-mail or e-books).
'e'+'gadget'='egadget'
'egadget' with 'get' removed is 'EGAD'.
Can you help me to learn more?
(Other definitions for egad that I've seen before include "My word once" , "Christ" , "Archaic exclamation of surprise" , "Old exclamation; aged (anagram)" , "Old oath" .)
