Coffee has initially been a food – chewed, not sipped. Early African tribes consume coffee by grinding the berries together, adding some animal fat, and rolling the treats into tiny edible energy balls.
HADRON
hadron
(noun) any elementary particle that interacts strongly with other particles

Etymology
Noun
hadron (plural hadrons)
(particle) A composite particle that comprises two or more quarks held together by the strong force and (consequently) can interact with other particles via said force; a meson or a baryon.
Usage notes
• Aside from individual quarks (which are never observed by themselves) hadrons are the only particles that interact via the strong force. Thus, a possible (though potentially slightly misleading) definition is "composite particle that can interact via the strong force" - or indeed simply "composite particle", as all hadrons are composite and all known non-hadrons are not known to be composite. Either definition however will be non-marginally wrong if the existence of the hypothetical "glueballs", non-hadronic composite particles consisting of gluons, is confirmed.
• The two categorisations hadron versus non-hadron and fermion versus boson together turn out to comprise a useful high-level categorisation of subatomic particles. (See the diagram above.)
(Missing from the diagram are quarks, the building blocks of hadrons. They are elementary, and therefore not themselves hadrons; they are, however, fermions. Thus, they would be classified, alongside leptons, as non-hadronic fermions.)
