Even a chemist develops triumphs (12)
I believe the answer is:
achievements
'triumphs' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'even a chemist develops' is the wordplay.
'develops' indicates anagramming the letters.
'even'+'a'+'chemist'='evenachemist'
'evenachemist' is an anagram of 'ACHIEVEMENTS'.
Can you help me to learn more?
(Other definitions for achievements that I've seen before include "Accomplishments" , "they're accomplished" , "Even a chemist (anag.)" .)
