中文词源
log 原木，航海日志，日志，计算机登录
词源不详，可能来自拟声词，大块物体滚动的隆隆声。在早期航海过程中，水手会在一根打结(knot)的长绳末端寄上一块原木，并通过绳结来计算船航行的速度并进行记录，因此，引申词义航海日志，记录，计算机登录等，而节则作为航海的速度单位流传下来。

英文词源
- log
- 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 (v.2)
- "to enter into a log-book," 1823, from log (n.2). Meaning "to attain (a speed) as noted in a log" is recorded by 1883. Related: Logged; logging.
- log (n.2)
- "record of observations, readings, etc.," 1842, sailor's shortening of log-book "daily record of a ship's speed, progress, etc." (1670s), from log (n.1). The book so called because a wooden float at the end of a line was cast out to measure a ship's speed. General sense by 1913.
- log (v.1)
- "to fell a tree," 1717; earlier "to strip a tree" (1690s), from log (n.1). Related: Logged; logging.
