Kernel of an idea (4)

Ross

I believe the answer is:

germ

'kernel of an idea' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for germ that I've seen before include "Disease-causing microorganism" , "Small organism that spreads disease" , "Cause of some diseases" , "Tiny organism that spreads disease" , "Bug" .)

I've seen this clue in The New York Times and the Newsday.com.
