lazaretto (n.): "house for reception of lepers and diseased poor persons," 1540s, from Italian lazareto "place set aside for performance of quarantine" (especially that of Venice, which received many ships from plague-infested districts in the East), from the Biblical proper name Lazarus. Meaning "building set apart for quarantine" is c. 1600 in English. The word in Italian was perhaps influenced by the name of another hospital in Venice, that associated with the church of Santa Maria di Nazaret.
period (n.): early 15c., "course or extent of time," from Middle French periode (14c.) and directly from Medieval Latin periodus "recurring portion, cycle," from Latin periodus "a complete sentence," also "cycle of the Greek games," from Greek periodos "cycle, circuit, period of time," literally "a going around," from peri- "around" (see peri-) + hodos "a going, way, journey" (see cede).

Sense of "repeated cycle of events" led to that of "interval of time." Meaning "dot marking end of a sentence" first recorded c. 1600, from similar use in Medieval Latin (in late 16c. English it meant "full pause at the end of a sentence"). Sense of "menstruation" dates from 1822. Educational sense of "portion of time set apart for a lesson" is from 1876. Sporting sense attested from 1898. As an adjective from 1905; period piece attested from 1911.
sanctuary (n.): early 14c., "building set apart for holy worship," from Anglo-French sentuarie, Old French saintuaire "sacred relic, holy thing; reliquary, sanctuary," from Late Latin sanctuarium "a sacred place, shrine" (especially the Hebrew Holy of Holies; see sanctum), also "a private room," from Latin sanctus "holy" (see saint (n.)).

Since the time of Constantine and by medieval Church law, fugitives or debtors enjoyed immunity from arrest in certain churches, hence transferred sense of "immunity from punishment" (late 14c.). Exceptions were made in England in cases of treason and sacrilege. General (non-ecclesiastical) sense of "place of refuge or protection" is attested from 1560s; as "land set aside for wild plants or animals to breed and live" it is recorded from 1879.
rosery: "A portion of a garden set apart for growing roses; a rose garden", Mid 18th cent. From rose + -ery, probably as an alteration of rosary.
