Feel it's what the greenhorn lacks (10)

I believe the answer is:

experience

I'm a little stuck... Click here to teach me more about this clue!

'feel' is the definition.
(I know that feel is a more specific form of experience)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for experience that I've seen before include "Go through" , "Encounter" , "Knowledge gained over time" , "What one has been through and is supposed to learn from" , "Try" .)
