log: [14] Log is a mystery word. It first turns up (in the sense ‘felled timber’) towards the end of the 14th century, but it has no ascertainable relatives in any other language. Nor is it altogether clear how the sense ‘ship’s record’ came about. It was inspired by the use of log for a thin piece of wood floated in the water from a line to determine the speed of a ship, but some etymologists have speculated that this is not the same word as log ‘piece of timber’, but was adapted from Arabic lauh ‘tablet’.
log (n.1)
unshaped large piece of tree, early 14c., of unknown origin. Old Norse had lag "felled tree" (from stem of liggja "to lie"), but on phonological grounds many etymologists deny that this is the root of English log. Instead, they suggest an independent formation meant to "express the notion of something massive by a word of appropriate sound." OED compares clog (n.) in its original Middle English sense "lump of wood." Log cabin (1770) in American English has been a figure of the honest pioneer since the 1840 presidential campaign of William Henry Harrison. Falling off a log as a type of something easy to do is from 1839.

log (n.2)
