The story

1. Proto-Germanic · derived from*sawwą“moisture, sap, juice”
2. Proto-Germanic · derived from*sawwijaz
3. Old Norse · derived from*sǫggr“moist, wet”
4. English todaysog

Of uncertain origin. Possibly of North Germanic origin; compare Icelandic söggur (“moist”), dialectal Norwegian søgg (“moist”), dialectal Swedish sögg, sygg (“something moist”), from Old Norse *sǫggr (“moist, wet”), suggested to be from Proto-Germanic *sawwijaz, a derivative of Proto-Germanic *sawwą (“moisture, sap, juice”), related to Old English ġesēaw (“full of moisture, soaked”), Old English sēaw (“moisture, juice, humour”). The verb is possibly related to soak. Potentially a doublet of sag, also of North Germanic origin; compare dialectal Danish sagge, Norwegian sagga, Swedish sagga, Faroese sagg (“to lag”), and dialectal Swedish sagga (“raining lightly”), Icelandic sagga (“to get damp”), and Old Norse síga, Old Norse sige, Swedish siga (“to sag, sink, slide; to ooze, seep, trickle; to move slowly, drift, glide”), and Old Norse seigr (“viscous”), Faroese seigur, Danish sej, Norwegian seig, Swedish seg (“tough, sluggish”), to the same root as Proto-Germanic *sīganą.
