chain

• n. 鎖；かせ；くびき
• vt.縛る；監禁する；鎖につなぐ

ラテン語のcatena（鎖）が語源で、語源的にはconcatenation（連結）と同じ。 tの文字が外れるので、bake, batch, wake,watchと比較される。

chain

chain: [13] Chain is a direct descendant of Latin catēna ‘chain’, source also of English concatenate [16], literally ‘link together in a chain’. This passed into Old French as chaeine, a later from of which, chaine, was adopted by English. The Latin word’s antecedents are not known.

chain (n.)

c. 1300, from Old French chaeine "chain" (12c., Modern French cha?ne), from Latin catena "chain" (source also of Spanish cadena, Italian catena), which is of unknown origin, perhaps from PIE root *kat- "to twist, twine" (cognates: Latin cassis "hunting net, snare").

Figurative use from c. 1600. As a type of ornament worn about the neck, from late 14c. Chain of stores is American English, 1846.
