Uncultivated — but you might pick up Oscar? (4)
I believe the answer is:
wild
'uncultivated' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for wild that I've seen before include "Impulsive" , "Undomesticated" , "Feral - crazy" , "unruly" , "Tempestuous" .)
