*teue-

Old English butere "butter, the fatty part of milk," obtained from cream by churning, general West Germanic (compare Old Frisian, Old High German butera, German Butter, Dutch boter), an early loan-word from Latin butyrum "butter" (source of Italian burro, Old French burre, French beurre), from Greek boutyron. This is apparently "cow-cheese," from bous "ox, cow" (from PIE root *gwou- "ox, bull, cow") + tyros "cheese" (from PIE root *teue- "to swell"); but this might be a folk etymology of a Scythian word.

The product was used from an early date in India, Iran and northern Europe, but not in ancient Greece and Rome. Herodotus described it (along with cannabis) among the oddities of the Scythians. In old chemistry, applied to certain substances of buttery consistency. Butter-knife, a small, dull knife used for cutting butter at the table, is attested from 1818.

"insolent, offensive, abusive speech," late 14c., from Old French contumelie, from Latin contumelia "a reproach, insult," probably derived from contumax "haughty, stubborn, insolent, unyielding," used especially of those who refused to appear in a court of justice in answer to a lawful summons, from assimilated form of com-, here perhaps an intensive prefix (see com-), + tumere "to swell up" (from PIE root *teue- "to swell").

The unhappy man left his country forever. The howl of contumely followed him across the sea, up the Rhine, over the Alps; it gradually waxed fainter; it died away; those who had raised it began to ask each other, what, after all, was the matter about which they had been so clamorous, and wished to invite back the criminal whom they had just chased from them. [Thomas Babington Macaulay, "Lord Byron," 1877]
