helpmate (n.)youdaoicibaDictYouDict[helpmate 词源字典]
"companion," 1715, altered from helpmeet, a ghost word, from the Biblical translation of Latin adjutorium simile sibi [Gen. ii:18] as "an help meet (i.e. fit) for him" (Hebrew 'ezer keneghdo), which already by 1673 was being printed as help-meet and mistaken for one word.[helpmate etymology, helpmate origin, 英语词源]
