braid: braid: [OE] The ultimate source of braid was West and North Germanic *bregthan, whose underlying meaning was probably ‘make sudden jerky movements from side to side’. This was carried through into Old English bregdan, but had largely died out by the 16th century. However, ‘making swift side-to-side movements’ had early developed a special application to the intertwining of strands or threads, and it is this ‘plaiting’ sense which has survived. The Germanic base *bregth- was also the ultimate source of bridle, but the superficially similar embroider had a different origin.
=> bridle, upbraid

knot (n.): Old English cnotta "intertwining of ropes, cords, etc.," from Proto-Germanic *knuttan- (cognates: Low German knütte, Old Frisian knotta "knot," Dutch knot, Old High German knoto, German Knoten, perhaps also Old Norse knutr "knot, knob"). Figurative sense of "difficult problem" was in Old English (compare Gordian knot). Symbolic of the bond of wedlock, early 13c. As an ornament of dress, first attested c. 1400. Meaning "thickened part or protuberance on tissue of a plant" is from late 14c.

The nautical unit of measure of speed (1630s) is from the practice of attaching knotted string to the log line. The ship's speed can be measured by the number of knots that play out while the sand glass is running.
The distance between the knots on the log-line should contain 1/120 of a mile, supposing the glass to run exactly half a minute. [Jorge Juan and Antonio de Ulloa, "A Voyage to South America" 1760]
Hence the word knot came also to be used as the equivalent of a nautical mile (in pre-WWII use in U.S. and Britain, 6,080 feet). A speed of 10 knots will cover ten nautical miles in an hour (equivalent to a land speed of about 11.5 mph).
navel (n.): Old English nafela, nabula, from Proto-Germanic *nabalan (cognates: Old Norse nafli, Danish and Swedish navle, Old Frisian navla, Middle Dutch and Dutch navel, Old High German nabalo, German Nabel), from PIE *(o)nobh- "navel" (cognates: Sanskrit nabhila "navel, nave, relationship;" Avestan nafa "navel," naba-nazdishta "next of kin;" Persian naf; Latin umbilicus "navel;" Old Prussian nabis "navel;" Greek omphalos; Old Irish imbliu). For Romanic words, see umbilicus.

"Navel" words from other roots include Lithuanian bamba, Sanskrit bimba- (also "disk, sphere"), Greek bembix, literally "whirlpool." Old Church Slavonic papuku, Lithuanian pumpuras are originally "bud." Considered a feminine sexual center since ancient times, and still in parts of the Middle East, India, and Japan. In medieval Europe, it was averred that "[t]he seat of wantonness in women is the navel." [Cambridge bestiary, C.U.L. ii.4.26] Words for it in most languages have a secondary sense of "center." Meaning "center or hub of a country" is attested in English from late 14c. To contemplate (one's) navel "meditate" is from 1933; hence navel-gazer (1952); see also omphaloskepsis. Navel orange attested from 1888.
twine (v.): "to twist strands together to form twine," c. 1300, from twine (n.) and probably also from Old Norse tvinna "to double." Sense of "to twist around something" (as twine does) is recorded from late 14c. Related: Twined; twining.
