help (v.)youdaoicibaDictYouDict[help 词源字典]
Old English helpan (class III strong verb; past tense healp, past participle holpen) "help, support, succor; benefit, do good to; cure, amend," from Proto-Germanic *helpan (cognates: Old Norse hjalpa, Old Frisian helpa, Middle Dutch and Dutch helpen, Old High German helfan, German helfen), from PIE root *kelb- "to help" (cognates: Lithuanian selpiu "to support, help").

Recorded as a cry of distress from late 14c. Sense of "serve someone with food at table" (1680s) is translated from French servir "to help, stead, avail," and led to helping "portion of food." Related: Helped (c. 1300). The Middle English past participle holpen survives in biblical and U.S. dialectal use.[help etymology, help origin, 英语词源]
help (n.)youdaoicibaDictYouDict
Old English help (m.), helpe (f.) "assistance, succor;" see help (v.). Most Germanic languages also have the noun form, such as Old Norse hjalp, Swedish hjälp, Old Frisian helpe, Dutch hulp, Old High German helfa, German Hilfe. Use of help as euphemism for "servant" is American English, 1640s, tied up in notions of class and race.
