A taste that is similar (5)
I believe the answer is:
alike
'is similar' is the definition.
(synonyms)
'a taste' is the wordplay.
'taste' becomes 'like' (I am not sure about this - if you are sure you should believe this answer much more).
'a'+'like'='ALIKE'
'that' is the link.
Can you help me to learn more?
(Other definitions for alike that I've seen before include "Equally" , "In a similar way" , "Similar, analogous" , "Undistinguished" , "Resembling each other" .)
