Attempt to keep objective and up-to-date (6)
I believe the answer is:
trendy
'up-to-date' is the definition.
(I've seen this in another clue)
'attempt to keep objective' is the wordplay.
'attempt to' becomes 'try' (I've seen this in other clues).
'keep' indicates putting letters inside.
'objective' becomes 'end' (both can mean a purpose).
'try' going around 'end' is 'TRENDY'.
'and' acts as a link.
(Other definitions for trendy that I've seen before include "Stylish" , "Less sensible; a dye plant" , "Cool" , "Informally fashionable" , "Fashionable, in style" .)
