cure [cure 词源字典]: cure: [13] The Latin noun cūra ‘care’ has fathered a wide range of English words. On their introduction to English, via Old French, both the noun and the verb cure denoted ‘looking after’, but it was not long before the specific sense ‘medical care’ led to ‘successful medical care’ – that is, ‘healing’ (the Latin verb cūrāre could mean ‘cure’ too, but this sense seems not to have survived into Old French).

The notion of ‘looking after’ now scarcely survives in cure itself, but it is preserved in the derived nouns curate [14] (and its French version curé [17]), who looks after souls, and curator [14]. The Latin adjective cūriōsus originally meant ‘careful’, a sense preserved through Old French curios into English curious [14] but defunct since the 18th century.

The secondary sense ‘inquisitive’ developed in Latin, but it was not until the word reached Old French that the meaning ‘interesting’ emerged. Curio [19] is an abbreviation of curiosity [14], probably modelled on Italian nouns of the same form. Curette [18] and its derivative curettage [19] were both formed from the French verb curer, in the sense ‘clean’.

Other English descendants of Latin cūra include scour, secure, and sinecure.

Siamese twins: Siamese twins: [19] The original ‘Siamese twins’ were two males, Chang and Eng (1811– 74), born in Siam (now Thailand), who were joined together at the hip. No attempt was made to separate them, and they lived to a respectable age; each married and fathered children. In an age unembarrassed to be interested in ‘freaks’, they gained considerable public attention, and by the 1850s Siamese twins seems to have established itself as a generic term. The late 20th century’s aversion from associating physical defects with racial or national groups has ousted it in favour of ‘conjoined twins’.
