Log

Etymology 1
18th century,.

Noun

 * 1)  log device for measuring a ship's speed

Usage notes

 * The plural should be spelt according to Duden (based on the principle that final consonants are not normally doubled in German inflections), but the spelling  appears at least equally justified (by analogy with the related terms with  and in order to avoid confusion with ). Neither of these seems common, however. If the plural must needs be expressed, the most sensible may be to use  (principally plural of the variant ).
