Ridiculous old woman having to abandon native (7)
I believe the answer is:
idiotic
'ridiculous' is the definition.
(I know that ridiculous can be written as idiotic)
'old woman having to abandon native' is the wordplay.
I cannot really see how this works, but
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is found in the answer.
'woman' could be 'di' (short for Diana) and 'di' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for idiotic that I've seen before include "Absurd, crackbrained" , "Half witted" , "Senseless" , "Silly" , "Altogether nonsensical" .)
