Odd in some unique, erudite way (5)
I believe the answer is:
queer
'odd' is the definition.
(I know that odd can be written as queer)
'some unique erudite way' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'QUEER' is hidden within 'unique erudite way'.
'in' acts as a link.
(Other definitions for queer that I've seen before include "Rum" , "Strange, curious" , "- - Street" , "Eccentric" , "Peculiar" .)
