köken: From Middle High German etewaʒ, from Old High German eddeshwaz, from edde- + hwaz. The first element is of obscure origin, but possibly related to Proto-Germanic *ehþau (“otherwise, or, but if”), source of modern oder (“or”). Compare Icelandic eitthvað, Dutch ietwat.
köken: From earlier -hka-i, from a dialectal variant of -kka (-ka) + -i. The -h- may be from *-eh (see -e). The suffix has been compared to Erzya -шка (-ška) (comparative case suffix), likely from Proto-Mordvinic *-ža + *-ka.
nuori (“young”) + -hko → nuorehko (“youthful, relatively young”)
vanha (“old”) + -hko → vanhahko (“oldish, relatively old, elderly”)
