1590s, Shakespearian back-formation of groveling (Middle English), regarded as a present participle but really an adverb, from Old Norse grufe "prone" + obsolete adverbial suffix -ling (which survives also as the -long in headlong, sidelong); first element from Old Norse a grufu "on proneness." Perhaps related to creep. Related: Groveled; grovelled; groveling; grovelling.
