umbrella
1609, first attested in Donne's letters, from It. ombrello, from L.L. umbrella, altered (by influence of umbra) from L. umbella "sunshade, parasol," dim. of umbra "shade, shadow" (see umbrage). A sunshade in the Mediterranean, a shelter from the rain in England; in late 17c. usage, usually as an Oriental or African symbol of dignity. Said to have been used by women in England from c.1700; the first rain-umbrella carried by a man there was traditionally c.1760, by Jonas Hathaway, noted traveler and philanthropist. Fig. sense of "authority, unifying quality" (usually in a phrase such as under the umbrella of) is recorded from 1948.
