ดิ้นรนขวนขวาย ภาษาอังกฤษ

From Middle English struglen, stroglen, strogelen, of obscure origin; perhaps from a variant of *strokelen, *stroukelen (> English stroll), from Middle Dutch struyckelen ("to stumble, trip, falter"; > Modern Dutch struikelen), the frequentative form of Old Dutch *strūkon (“to stumble”), from Proto-Germanic *strūkōną, *strūkēną (“to be stiff”), from Proto-Indo-European *strug-, *ster- (“to be stiff; to bristle, strut, stumble, fall”), Cognate with Scots strugil (“to struggle, grapple, contend”). Also related to Middle Low German strûkelen ("to stumble"; > Low German strükeln), Old High German strūhhēn, strūhhōn ("to stumble, trip, tumble, go astray"; > German strauchen, straucheln). Alternative etymology derives the base of struggle from Old Norse strúgr (“arrogance, pride, spitefulness, ill-will”) + -le (frequentative suffix), from Proto-Germanic *strūkaz (“stiff, rigid”), ultimately from the same Proto-Indo-European root above, which would make it cognate with dialectal Swedish strug (“contention, strife, discord”), Norwegian stru (“obstinate, unruly”), Danish struende (“reluctantly”), Scots strug (“difficulty, perplexity, a laborious task”).
