Ah, one of our all-time favorite patterns and examples: leche, the common Spanish word meaning, “milk.”
Leche is a first cousin of the English lactose via a very interesting pattern: the ‑ct- to ‑ch- pattern.
Both come from the same Latin root, lactatio (literally, “suckling.”) The ‑ct- in that root remained unchanged as it entered English (because it entered via the sophisticated French) but that sound almost always turned into a ‑ch- sound as Latin evolved into Spanish. Thus the l‑ct maps to the l‑ch almost exactly.
Many other awesome words follow the same pattern: think octagon/ocho, for example. Some more coming up soon (or see the pattern page linked below).
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.
Lighthouse in Spanish is Faro. Seems totally random, doesn’t it? Well…
The greatest and most famous lighthouse in history was, of course one of the 7 Wonders of the World, the infamous Lighthouse at Alexandria, in ancient Egypt.
And the ancient Latins — knowing all about and in awe of the amazing lighthouse- referred to it by the title of the man who built it which was, of course, the King of Egypt. And they called their Kings, Pharaohs!
Pharaoh — yes, the same Pharaoh featured in the Old Testament who enslaved the Jews and thus of course gave them the holiday of Passover — in Spanish is written faraón. Thus, giving rise to the word faro for lighthouse.
