The Spanish hilo (cord; thread; string) comes from the Latin for the same, filum. The words sound very different, until we remember that, words in Latin that began with a f- tended to change to h- in Spanish: hijo/filium, and hoja/foliage, for example. Now the hilo/filum make sense!
Interestingly, however, from that same Latin root filum, we get various English words that also quietly show they are descendants of the word for cord or thread. Including:
The Spanish for syrup, jarabe, comes from the same root as the English: the Persian/Arabic sharab, which means “a drink, or wine”.
The drastically different (at least superficially) words are explained by the sh- and related (such as, sy- ) sounds changing to the Arabic-sounding j- sound in Spanish — but not English.
Thus, the j‑r-b of jarabe maps to the sy-r‑p of syrup.
So, this is one of my personal all-time favorite etymologies. Just sayin’.
The Spanish for “heart,” corazón, and the English heart itself, both come from the same original root.
Huh? How? But they’re so different!
Both come from the Proto-Indo-European *kerd-, meaning the same. The key to understanding this one is remembering the pattern that the k- sounds from PIE tended to remain the same in Latin, but changed to the h- sound as it evolved into German and then English. Take, for example, hundred/century, for example.
Thus, the h‑r-t of heart maps to the c‑r-z of corazón.
From the same root is… courage. yup, that c‑r is the same c‑r. So courage is indeed something that comes from the heart.
The Latin sounds for “sh” — and similar variations, like “ch” and “ss” — became a “j” sound in Spanish.
Thus, the English sherry is near identical to the Spanish jerez!
These sh/j sounds were often spelt with a “x” in old Spanish; and sherry itself is named after the town it first came from, Xeres, which is near Cordova.
Enojar, Spanish for “to get angry”, has a fun cousin in the English, annoy.
Both of these (along with the French for “worldly boredom”, ennui) come from the Latin inodiare, meaning, “to hate”. The Latin in- adds emphasis to the odium, Latin for “hate”.
We can see the parallels in all with the open vowel, followed by the ‑n-, followed by a ‑y- sound, although in Spanish the ‑y- sounds (and its corresponding ‑x- and ‑sh- variations) often turned into the ‑j- sounds, as it did here. Thus, the a‑n-y maps to the e‑n-j.
Hatred, then, dissipates and weakens over time. In English, hatred weakens into mere annoyance. In Spanish, hatred weakens into just anger, enojo. And, best of all, hatred in French weakens into a world-weary boredom of ennui.
