increase: [14] The -crease element in increase (which occurs also, of course, in its antonym decrease) means ‘grow’. It comes from Latin crēscere ‘grow’ (source of English crescent), which combined with the prefix in- to produce incrēscere ‘grow in, grow on’. This passed into Old French as encreistre, which English originally took over as encres. The Latin-style spelling, with in- instead of en-, was reintroduced in the 15th century. Derived from Latin incrēscere was incrēmentum ‘growth, increase’, which gave English increment [15].
=> crescent, crew, croissant, decrease, increment[increase etymology, increase origin, 英语词源]

nail: [OE] The Indo-European ancestor of nail was *nogh- or *onogh-. The latter was the source of Latin unguis (which evolved into French ongle and Italian unghia and has given English ungulate [19]) and Greek ónux (source of English onyx). Both these strands refer only to the sort of nails that grow on fingers and toes, but the Germanic branch of the family (which has come from *nogh- through a prehistoric Germanic *naglaz) has differentiated into a ‘fastening pin’ – originally of wood, latterly of metal.

Hence English nail and German nagel cover both meanings (although Dutch and Swedish nagel and Danish negl are used only for the anatomical ‘nail’).
=> onyx, ungulate

Have you ever heard anything about God, Topsy? ... Do you know who made you?" "Nobody, as I knows on," said the child. ... "I spect I grow'd. Don't think nobody never made me." [Harriet B. Stowe, "Uncle Tom's Cabin," 1851]
