‘lion’: a person of note or celebrity who is much sought after—from ‘lions’: things of note, celebrity, or curiosity in a town, etc.—from the practice of taking visitors to see the lions which used to be kept in the Tower of London
‘the lion’s share’ (UK, 1790)—calque of French ‘le partage du lion’ (now ‘la part du lion’)—from ‘The Heifer, the She-Goat, and the Ewe, in partnership with the Lion’, a fable by Jean de La Fontaine (1621-95)
meaning: ‘thoroughly dejected or disappointed’—appeared (1973) in Tyne and Wear (north-eastern England)—originated apparently in football parlance, in which it soon became a cliché
UK, 1832—‘the awkward age’: the adolescence, when one is no longer a child but not yet properly grown up, a time of life characterised by physical and emotional changes—translates in French as ‘l’âge ingrat’, ‘the thankless age’
USA, 1917 (with ‘footie’): to touch somebody’s foot lightly with one’s own foot, especially under a table, as a playful expression of romantic interest—hence also, figuratively: to have underhanded dealings with somebody
‘double Dutch’, 19th century—from ‘Dutch’ in the sense of a language that few people can speak, and ‘double’ as a mere intensifier—‘High Dutch’, 17th century—loan translation from French ‘haut allemand’ (= ‘High German’), used in the sense of gibberish

1763 in French, 1798 in English—from the name of Étienne de Silhouette (1709-67), Controller-General of Finances in 1759—perhaps because he might have invented the portrait in profile obtained by tracing the outline of a head or figure by means of its shadow
After Ambrose Burnside, Union general in the U.S. Civil War, ‘burnsides’ (1866) denotes thick side whiskers worn with a moustache and clean-shaven chin; on the pattern of ‘side whiskers’, it was altered to ‘sideburns’ (1875), itself altered to ‘sideboards’ (1882).
‘coward’—from Old-French ‘cuard’, probably referring to a frightened animal with its tail between its legs—from ‘cüe’ (Modern French ‘queue’), ‘tail’, and pejorative suffix ‘-ard’ (cf. ‘bastard’)—‘cowardy, cowardy custard’, alliterative nonsensical children’s phrase (19th century)
