Undemanding force in English stronghold changing sides (10)
I believe the answer is:
effortless
'undemanding' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'force in english stronghold changing sides' is the wordplay.
I cannot quite see how this works, but
'force' could be 'f' (scientific abbreviation) and 'f' is found within the answer.
'english' could be 'e' (abbreviation) and 'e' is found within the answer.
'stronghold' could be 'fort' (I've seen this before) and 'fort' is found within the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for effortless that I've seen before include "Not showing any strain" , "Requiring no physical or mental exertion" , "a breeze?" , "easy" .)
