Try a test another way (5)
I believe the answer is:
taste
'try' is the definition.
(I know that try can be written as taste)
'a test another way' is the wordplay.
'another way' is an anagram indicator.
'a'+'test'='atest'
'atest' anagrammed gives 'TASTE'.
(Other definitions for taste that I've seen before include "Small sample of food" , "Appreciation, discernment" , "Judgment" , "eat only the smallest amount" , "Perceive the flavour" .)
