词源

The noun is derived from Middle English pith, pithe (“soft interior; pith, pulp”) [and other forms], from Old English piþa [and other forms], from Proto-Germanic *piþô, from earlier *piþō (oblique *pittan); further etymology unknown. Doublet of pit (“seed or stone inside a fruit”). The verb Middle English pethen (“to give courage or strength”), derived from the noun pith (noun), did not survive into modern English. Cognates * Dutch peen (“carrot”) * Middle Low German peddek, peddik, piddek (“bone marrow; medulla; spinal cord; inner part of a horn or quill; (figurative) core, essence”) (the last spelling rare) (Low German Peddik (“core; pulp”)) * West Frisian piid (“pulp, kernel”)
