Sueño (Spanish for “dream”) and insomnia come from the same root: the Latin somnus, meaning, “sleep.”
The evolution is easy to spot if we remember that the ‑mn- sound in Latin usually transformed into the ñ in Spanish. See damn and daño, for example. Or autumn and otoño as well.
Thus, the s‑mn of insomnia maps to the s‑ñ of, sueño.
Cuello (Spanish for “neck”) comes from the Latin collum, also meaning “neck.” From collum, we get the English… collar. We can see the c‑ll mapping in both.
More interesting, though, is from that same root, we also get the English accolades, which is just collum with the classic Latin ad- (“towards”) prefix.
How did we get from “towards the neck” to “giving honors and awards”? Well, accolades was originally used in the sense of, resting the sword on your shoulder–like the King does to you when he turns you into a knight. Being knighted was the ultimate honor you could receive, with the king bestowing it by placing the sword on your shoulder.
Since medieval times, apparently, honors have become increasingly easy to give and receive, since know we get accolades for every little “job well done”!
We’ve previously discussed cuerno (Spanish for horn) and its related Spanish words–and here’s another: cornucopia, which literally means… the “horn of plenty.” We see the h‑r-n map to the c‑r-n again here!
The English for eager-to-fight, pugnacious, contains the ‑gn- pattern inside it: a give-away to the pattern that ‑gn- words in Latin turned the ‑gn- into a ‑ñ- in Spanish yet remained the same into English.
Therefore, pugnacious maps perfectly to puñal, the Spanish for… “dagger.” It makes sense that “dagger” and “eager to fight” come from the same root, after all. And that root, in this case, is the Latin pugnare, meaning, “to fight.”
Superseer (Spanish for, “to discontinue; cease”) comes from the Latin supersedere which in term is a combination of the prefix super- (“above”) and sedere (“to sit”). When you stop doing something — you’re now, literally, sitting on top of it. At least in Spanish.
From the Latin sedere root, we get various English words related to sitting, including:
From the same Latin root sedere we also get the Spanish… asiento, the common word for, seat. Now that makes sense, doesn’t it?
The s‑n-t/d root is visible in most of these words. Note that in superseer, the middle ‑n- disappeared: hence the ‑e- on both sides!
