Ring denies adaptation is primarily discriminatory or lacking in balance (3-5)
I believe the answer is:
one-sided
'or lacking in balance' is the definition.
I can't tell whether this defines the answer.
'ring denies adaptation is primarily discriminatory' is the wordplay.
'ring' becomes 'o' (letter resembling a ring).
'adaptation' is an anagram indicator.
'is primarily' indicates taking the first letters.
The initial letter of 'discriminatory' is 'd'.
'denies' with letters rearranged gives 'neside'.
'o'+'neside'+'d'='ONE-SIDED'
Can you help me to learn more?
(Other definitions for one-sided that I've seen before include "Biased, favouring one part over another" , "So denied being unfair or biased" , "Unbalanced" , "Unfair or uneven" , "Indeed so (anag.)" .)
