Origin of compound

1
First recorded in 1350–1400; Middle English verb componen, compounen, compownen, from Old French compon- (stem of compondre ), from Latin compōnere, equivalent to com- com- + pōnere “to put”; Middle English adjective compouned, past participle of componen, as above

historical usage of compound

The English verb compound, first appearing in Middle English in the late 14th century as compounen, compownen, comes from Old French compondre, compundre “to direct, arrange,” from Latin compōnere “to put together, add together, match, match up.” The adjective compound, originally a past participle of the verb, is also recorded at the end of the 14th century. The noun, a development of the adjectival sense, is recorded considerably later, in the first half of the 16th century.
The final, unetymological -d in compound arose during the 16th century; it is of the same origin as the -d in the English word sound (meaning “noise”), which developed from the earlier English soun (from Old French son, from Latin sonus ), and the archaic verb round “to whisper,” a derivative of rune “a secret.”

Origin of compound

2
First recorded in 1670–80; alteration, by association with compound1, of Malay kampung “village, collection, gathering”; cf. kampong

historical usage of compound

The noun compound “a large, enclosed area” most likely comes from Malay kampong, kampung “fenced-in space, enclosure, village, a part of town inhabited by a particular nationality.” Compound originally referred to the European (originally Portuguese, Dutch, English) complexes of residences, factories, and warehouses in the East Indies, India, and China. Kampong, kampung was associated in English with the noun compound “something consisting of several parts” by 1679, when the sense “a large, enclosed area” is first recorded. The term was also used in the 19th century to describe a similar confined living area for African laborers, especially miners. By the mid-20th century, the sense of “large, walled-in space in a prison or other detention camp” first appears.
