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 Indo-European root kaput, meaning “head”, led to words for the head in almost every western language, with no change.
The kaput turned into the almost-identical caput in Latin; and then that evolved, through very minor changes, to the almost-the-same cabeza in Spanish. The main sound shift is the p to b, but those are very clearly aligned signs that often swap.
Kaput, however, evolved into the German kopf — which then became the English head. How so?
The Germanic sound “k-”, as German evolved into English, generally became the “h-” sound in English. Take century/hundred or horn/cornudo or, my favorite, hemp/cannabis as other examples.
Thus, the c‑b(-z) of cabeza maps to the h‑d of head. In the English pattern of short, powerful words, the final sound was lost as well, to give us the simple, straightforward head.
The Spanish for “horn”, cuerno (and its variations, like the ever-present cornudo), and the English horn are both originally the same word in the ancient languages.
One of the most interesting sound shifts is the Indo-European “k-” sound remained the same into Latin and then Spanish (the Latin cornu for the same) but became an almost-silent “h-” in the Germanic languages.
Thus the c‑r-n in Spanish parallels exactly the h‑r-n in English.
There are lots of awesome and subtle examples of this pattern, such as Corazon/Heart.
Today’s link is another gem: despite sounding completely different, hundred and its ciento are actually the same word. Here’s how.
The ancient Proto-Indo-European root *kmtom meant a hundred. As PIE evolved into Latin, the word stayed basically the same phonetically, turning into centum, and stayed the same (but with a soft‑c pronunciation) into the Spanish, ciento.
But as PIE evolved into German, the k-/c- sounds evolved into h- sounds. Think about heart/corazon and hemp/cannabis, for example. 100 followed the same pattern, with the initial k-/c- sound turning into the h-.
Thus, the c‑n-t of ciento maps exactly to the h‑n-d of hundred. The t/d were interchanged but that’s a very common, similar, and more obvious pattern.
The Spanish correr, “to run” seems completely unrelated to the English horse. Looks can be deceiving.
Correr comes from the Latin for the same, currere. Currere, in turn, comes from the Proto-Indo-European root *kurs, which also means, “to run” — just like horse does! Both have the same common ancestor.
The weird thing is: how did the PIE *kurs turn into horse, they sound so different.
The explanation is that, in the Germanic languages like English, the k- sound turned into the h- sound. But in Spanish, the original k- sound remained, although usually written with a c-.
This explains many parallel words that have c- and h- sounds that map to each other between Spanish and English, like heart/corazon and head/cabeza.
