means To breathe with a harsh, rasping or grunting sound during sleep, caused by the vibration of soft tissue in the throat as air passes through a partly obstructed airway.

from From Middle English snoren, 'to snort,' and ultimately imitative — a word built from the very noise it names, part of a whole snorting, snoring, sneezing family of Germanic 'sn-' words that all start at the nose. Its cousins live on in Dutch snoren and German schnarchen; the 'sn-' cluster has been doing nasal duty across the Germanic tongues for a very long time.
