名词后缀-kin 来源有好几种一说来源于中古荷兰语-kin，跟德语里的后缀-chen 等价

英文词源：
diminutive suffix, first attested late 12c. in proper names adopted from Flanders and Holland, probably from Middle Dutch -kin, properly a double-diminutive, from -k + -in. Equivalent to German -chen. Also borrowed in Old French as -quin, where it usually has a bad sense.

This suffix, which is almost barren in French, has been more largely developed in the Picard patois, which uses it for new forms, such as verquin, a shabby little glass (verre); painequin, a bad little loaf (pain);

Pierrequin poor little Pierre, &c. ["An Etymological Dictionary of the French Language," transl. G.W. Kitchin, Oxford, 1878]

Used in later Middle English with common nouns. In some words it is directly from Dutch or Flemish.
