2306: magic & machine Apr 9, 2021

Although magic and science don't have much to do with each other, 'magic' and 'machine' are etymologically related. Indeed, the Proto-Indo-European root includes not only words directly adjacent to those before like 'mage', 'magi' and 'mechanism', but also 'may' and its derivatives, along with 'might' (both senses). The root '*magh-' is estimated to have had the meaning of 'ability' or 'power'. 'Main' is also among these with this common root. The sense of 'magic' in a purely sorcerous sense really comes from the 14th century, though in the sense of being an illusionist by trade without any actual spiritual component, the early 19th century.

2152: man Nov 5, 2020

One of the oldest and certainly significant root across all Indo-European languages is 'man'. For sure it has broad-reaching senses that gave us many modern derivatives, but not only is it unclear where it comes from, but also across Germanic languages it pushed out an earlier word 'wer'. One theory on its origin connects it to another root *men- giving 'mind' and more obviously the Latin 'mēns', hence 'mention', 'admonish', 'demonstrate', and 'automatic' through Greek, but other linguists contest this idea. Another theory points to Germanic mythology involving a figure known in Latin as Mannus who was the progenitor of people, known in the language as *Mannaz. Either way, it was used as a generic term for humanity and the pronominal use—still seen in German 'man' for 'one'—before it pushed out 'wer' (hence 'werewolf') as a word for 'man' (as in male) by the 13th century. This process is similar to the generic Latin term 'homo' (hence the French 'homme') pushing out 'vir' for specifically male. In all these words though, it also had the sense of 'husband'.

818: Giving and Taking in PIE (nimble and metronome) Mar 5, 2017

There are no known writings of the people who spoke Proto-Indoeuropean; in fact, there are still a number of disputes as whether they came from modern-day Ukraine or Anatolia, but through some linguistic clues, people can start to gain some idea of the culture of this people. For example, words meaning 'to take' in one language, and 'to give' in other Indo-European languages often are cognates of each other, which perhaps means that they were related culturally. This is evidenced in a somewhat surprising pair of words: 'metronome' and 'nimble'. The latter comes from the Old English 'nǣmel' meaning, ‘quick to seize or comprehend,’ and is related to 'niman' which meant ‘take’; the -B- was added to 'nimble' as it is is easier to pronounce that way. While 'niman' is related to a number of other Germanic words, it is also related to the Greek, 'nemein' meaning, 'distribute' or 'manage', and along with that, it is related to the Greek word for 'law', 'nomos'. 'Metronome', on the other hand, is an early 19th century that comes from a compound of the the Greek 'metron' meaning ‘measure’ and the aforementioned 'nomos' in the sense of "giving out". The relationship between giving and taking through this Proto-Indoeuropean root could signify their acknowledgement of that connection inherent in bartering.
