north

north: [OE] North is a general West and North Germanic word for ‘north’, represented also in German, Swedish, and Danish nord and Dutch noorden. It was also borrowed into French (from Old English) as nord, from where it spread into Italian and Romanian as nord and into Spanish as norte. It is not known for certain where it came from, but a link has been suggested with nertro-, a word for ‘left’ in the extinct Oscan- Umbrian languages of Italy, which might mean that the underlying meaning of north is ‘to the left as one faces the rising sun’ (modern Irish tuaisceart ‘north’ was based on a word meaning ‘left’).

north

Old English norð "northern" (adj.), "northwards" (adv.), from Proto-Germanic *nurtha- (cognates: Old Norse norðr, Old Saxon north, Old Frisian north, Middle Dutch nort, Dutch noord, German nord), possibly ultimately from PIE *ner- (1) "left," also "below," as north is to the left when one faces the rising sun (cognates: Sanskrit narakah "hell," Greek enerthen "from beneath," Oscan-Umbrian nertrak "left"). The same notion underlies Old Irish tuath "left; northern;" Arabic shamal "left hand; north." The usual word for "north" in the Romance languages ultimately is from English, for example Old French north (Modern French nord), borrowed from Old English norð; Italian, Spanish norte are borrowed from French.

Ask where's the North? At York 'tis on the Tweed;
In Scotland at the Orcades; and there
At Greenland, Zembla, or the Lord knows where.
[Pope, "Essay on Man"]

As a noun, c. 1200, from the adverb. North Pole attested from mid-15c. (earlier the Arctic pole, late 14c.). North American (n.) first used 1766, by Franklin; as an adjective, from 1770.
