#hriz- vb. "to snow", impersonal, given in the form hríza "it is snowing". Normally z would turn to r in Exilic Quenya, but since two r's close to one another were disliked, it may be that hriz- became *hris- instead (compare razë "sticks out" becoming rasë instead of **rarë, PE19:73) Past tense hrinsë (with s from the original root SRIS) and another form which the editor tentatively reads as hrissë (the development ns > ss is regular). (PE17:168)
