Etymology
From Middle English grinnen, from Old English grennian, from Proto-West Germanic *grannjōn, from Proto-Germanic *granjōną. Related to groan. Compare to Middle High German grennen (“to mutter, complain”) and Danish grine (“to show one's teeth, to laugh”)
From Middle English grin, grinne, grine, from Old English grin (“snare, noose”), of uncertain origin, but probably from the merger of Proto-West Germanic *garni and *garnī (“intestine”), ultimately from Proto-Germanic *garniz, *garnō (“guts, intestine”). Related to English yarn.
