Word Origin and History for umbrellalike



c.1600, first attested in Donne's letters, from Italian ombrello, from Late Latin umbrella, altered (by influence of umbra) from Latin umbella "sunshade, parasol," diminutive 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. Figurative sense of "authority, unifying quality" (usually in a phrase such as under the umbrella of) is recorded from 1948.
