Origin of log

From Middle English logge, logg (first recorded in Anglo-Latin as loggum), of uncertain origin, but probably from Old Norse lóg, lág (“felled tree, log”), derived from Old Norse liggja (“to lie”). If so, then cognate with Norwegian låg (“fallen tree”), Dutch loog (“wood, timber, lumber”). Alternatively, directly from Norwegian låg (“fallen tree”), which could have been borrowed through the Norwegian timber trade. However the Old Norse/Middle Norwegian vowel is long while Middle English vowel is short.

Clipping of logbook, itself from log (etymology 1) + book, from a wooden float (chip log) used to measure speed.

Ellipsis of log out, itself from Etymology 2.
