Oath once occasionally seen in England? (4)
I believe the answer is:
egad
'oath once' is the definition.
(historical oath)
'occasionally seen in england?' is the wordplay.
I cannot quite understand how this works, but
'england?' could be 'e' (short for England) and 'e' is located in the answer.
The remaining letters 'gad' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for egad that I've seen before include "Old oath" , "My word once" , "Forgotten curse" , "Old exclamation; aged (anagram)" , "Christ" .)
