New German number 3 intercepting a tiny bit (8)
I believe the answer is:
neutrino
'bit' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for neutrino that I've seen before include "Subatomic particle, now said to travel faster than light" , "There's almost nothing to it!" , "Tiny thing not charged" , "Minute item lacking mass" , "Small piece of matter" .)
