What is the X in X-mas?
c.1400 (late 12c. as a surname), from Old French pesche "peach, peach tree" (Old North French peske, Modern French pêche), and directly from Medieval Latin pesca, from Late Latin pessica, variant of persica "peach, peach tree," from Latin malum Persicum, literally "Persian apple," translating Greek Persikon malon, from Persis "Persia" (see Persian).
In ancient Greek Persikos could mean "Persian" or "the peach." The tree is native to China, but reached Europe via Persia. By 1663 William Penn observed peaches in cultivation on American plantations. Meaning "attractive woman" is attested from 1754; that of "good person" is from 1904. Peaches and cream in reference to a type of complexion is from 1901. Peach blossom as a color is from 1702. Georgia has been the Peach State since 1939.
"to inform against," 1560s (earlier "to accuse, indict, bring to trial," mid-15c.), a shortening of appeach, an obsolete variant of impeach. Related: Peached; peaching.
