No longer just one confusing sample (8)
I believe the answer is:
examples
'no longer just one confusing' is the definition.
I can't tell whether this defines the answer.
'sample' is the wordplay.
I cannot really understand how this works, but
an anagram of 'sample' is 'amples' which is present in the answer.
The remaining letters 'ex' 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 examples that I've seen before include "They illustrate general rules" , "Things characteristic of their kind" , "Representative samples" , "Expels ma for pieces of conduct worthy of imitation" , "Illustrative warnings" .)
