Eager to learn (7)
I believe the answer is:
curious
'eager to learn' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for curious that I've seen before include "Odd, rum" , "Eager to know something, perhaps nosy" , "Strange - inquisitive" , "with a great deal of interest!" , "Unusual; eager to learn" .)
