Allegiance is a very Roman idea: strong loyalty to your team, your empire.
So it’s not surprising that the word itself comes from the Latin, ligare — to bind. Your allegiance is what binds you or ties you to your team.
From the Latin ligare, we get the Spanish… ligar, meaning the same, tying or binding!
Thus, the l‑g root is clearly visible in both versions.
Salir, the common Spanish word meaning, “to leave” sounds like it has nothing to do with anything. Or does it?
Salir comes from the Latin salire meaning the same, “to jump”. Surprise, surprise.
From this same Latin root was get a bunch of fun English words, including:
We also get another Spanish word from the same root: saltar (“to jump”). You can see the s‑l mapping across all descendants of the word!
Lazar (Spanish for “to tie, such as with a ribbon”) comes from the Latin laqueum, meaning “a tie, such as a noose”. From that same root, we get the English… lasso. A lasso, after all, is really a cable that can be used to tie someone or something up…!
The l‑z of lazar clearly maps to the l‑ss of lasso.
The Spanish cobrar (“to charge”; in the sense of, to charge a fee or collect a payment) comes from the older Spanish recobrar (meaning, “to recuperate”) — which itself comes from the Latin recuperare for the same “to recuperate.”
We can see the c‑b-r mapping to the c‑p-r clearly, since the ‑c- and ‑p- are often interchanged.
Lesson: charging for something is really just recuperating money that is owed to you anyway!
Gremio (Spanish for “union,”, in the sense of workers, unite!; formerly “guild”–which is really just an old-school union!) comes from the Latin Gremium, meaning “round.” How did this transformation happen? Well, a round pen was where you held onto things; it turned into the word for where people got together, which turned into guild (a common reason people got together!) and then, eventually, to mean union.
However, it gets much more interesting. The Latin gremium comes from the proto-indo-european root *ger- meaning.… to get together! From this root, we also get (via Greek) words like congregate (to bring people together) and segregate (to bring people apart!).
Thus, gremio took an interesting turn over the last few thousand years: from the meaning congregate to round to congregate again!
We can see the g‑r root clearly in gremio as well as congregate and segregate.
