Obscure thing is made visible (2,5)
I believe the answer is:
in sight
'visible' is the definition.
(similar in meaning)
'obscure thing is' is the wordplay.
'obscure' indicates anagramming the letters.
'thing'+'is'='thingis'
'thingis' with letters rearranged gives 'IN SIGHT'.
'made' acts as a link.
(Other definitions for in sight that I've seen before include "just ahead" , "Visible" , "Within view" .)
