Also from the same source are Swedish bomull, Danish bomuld "cotton," and, via Turkish forms, Modern Greek mpampaki, Rumanian bumbac, Serbo-Croatian pamuk. German baumwolle "cotton" probably is from the Latin word but altered by folk-etymology to look like "tree wool." Polish bawełna, Lithuanian bovelna are partial translations from German.

From stuffing and padding for clothes or upholstery, meaning extended to "pompous, empty speech" (1580s).
Bombast was originally applied to a stuff of soft, loose texture, once used to swell the garment. Fustian was also a kind of cloth of stiff expansive character. These terms are applied to a high, swelling style of writing, full of extravagant sentiments and expressions. Bathos is a word which has the same application, meaning generally the mock heroic--that "depth" into which one falls who overleaps the sublime; the step which one makes in order to pass from the sublime to the ridiculous.

c. 1300, "in a state of a serf, unfree," from bond (n.) "tenant, farmer holding land under a lord in return for customary service; a married bond as head of a household" (mid-13c.). The Old English form was bonda, bunda "husbandman, householder," but the Middle English word probably is from Old Norse *bonda, a contraction of boande, buande "occupier and tiller of soil, peasant, husbandman," a noun from the past participle of bua, boa "to dwell" (from PIE root *bheue- "to be, exist, grow").

"In the more despotic Norway and Denmark, bo'ndi became a word of contempt, denoting the common low people. ... In the Icelandic Commonwealth the word has a good sense, and is often used of the foremost men ...." [OED]. The sense of the noun deteriorated in English after the Conquest and the rise of the feudal system, from "free farmer" to "serf, slave" (c. 1300) and the word became associated with unrelated bond (n.) and bound (adj.1).
