log
発音
語源 1
From Middle English logg, logge (first recorded in Anglo-Latin as loggum), of uncertain origin[1], 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.[2] However the Old Norse/Middle Norwegian vowel is long while Middle English vowel is short.[3]

語源 4
From Hebrew לֹג.
名詞
- (historical units of measure) A Hebrew unit of liquid volume (about 1⁄3 liter).
- 1902, Jewish Encyclopedia, s.v. "Weights and Measures":
- In the Hebrew system the log (Lev. xiv. 10) corresponds to the mina. Since the Hellenistic writers equate the log with the Græco-Roman sextarius, whatever these writers say on the relation of the sextarius to other measures applies also to the relation of these measures to the log. The log and the sextarius, however, are not equal in capacity. The sextarius is estimated at .547 liter, while there is no reason to regard the log as larger than the Babylonian mina, especially as other references of the Greek metrologists support the assumption that the log was equal to the mina. The fact that in the Old Testament the log is mentioned only as a fluid measure may be merely accidental, for the dry measures, which are distinguished in all other cases from the liquid measures, also have the log as their unit. The corresponding dry measure may, however, have been known under a different name.
