"the seed of a hardy leguminous vine," a well-known article of food, early or mid-17c., a false singular from Middle English pease (plural pesen), which was both single and collective (as wheat, corn) but the "s" sound was mistaken for the plural inflection. From Old English pise (West Saxon), piose (Mercian) "pea," from Late Latin pisa, variant of Latin pisum "pea," probably a loan-word from Greek pison "the pea," a word of unknown origin (Klein suggests it is from Thracian or Phrygian).
In Southern U.S. and the Caribbean, used of other legumes as well. Pea soup "soup made from peas" is recorded by 1711 (as pease-soup); the term was applied to London fogs at least since 1849. Pea-green as a hue resembling fresh peas is by 1752. Pea-shooter "toy consisting of a long straw or tube through which dried peas may be blown" is attested from 1803.
"heavy coat generally worn by sailors in cold or stormy weather," 1721, a partial loan-translation of North Frisian pijekkat, from Dutch pijjekker, from pij "coarse woolen cloth" + jekker "jacket." Middle English had pee "coat of coarse, thick wool" (late 15c.). Related: Pea-coat.
mid-12c., pes, "freedom from civil disorder, internal peace of a nation," from Anglo-French pes, Old French pais "peace, reconciliation, silence, permission" (11c., Modern French paix), from Latin pacem (nominative pax) "compact, agreement, treaty of peace, tranquility, absence of war" (source of Provençal patz, Spanish paz, Italian pace), from PIE root *pag- "to fasten" (which is the source also of Latin pacisci "to covenant or agree;" see pact), on the notion of "a binding together" by treaty or agreement.
It replaced Old English frið, also sibb, which also meant "happiness." The modern spelling is from 1500s, reflecting vowel shift. From mid-13c. as "friendly relations between people." The sense of "spiritual peace of the heart, soul or conscience, freedom from disturbance by the passions" (as in peace of mind) is from c. 1200. Sense of "state of quiet or tranquility" is by 1300, as in the meaning "absence or cessation of war or hostility." Specifically as "treaty or agreement made between conflicting parties to refrain from further hostilities," c. 1400.
Used in various greetings from c. 1300, from Biblical Latin pax, Greek eirēnē, which were used by translators to render Hebrew shalom, properly "safety, welfare, prosperity." As a type of hybrid tea rose (developed 1939 in France by François Meilland), so called from 1944.
