Learning Spanish & Etymology Pattern-Matching for Nerds
The Spanish for “foam”, espuma, comes from the Latin for the same: spuma. And this Latin comes from the Proto-Indo-European root *(s)poi-moi from which we also get the English… foam.
How so? Because the PIE root p- very consistently became an f- as it evolved into German then English, but this transformation never happened when it became Latin and then Spanish. Note words like foot/pie and father/padre.
Thus the f-m of foam maps to the (s)-p-m of espuma very clearly!
The relation between “five” in Spanish (cinco) and English is one of the more surprising relationships: they are indeed direct second cousins!
Both come from the same Proto-Indo-European root, *penkwe, meaning the same, five. (The greek for five also comes from the same: think about pentagon, for example).
The interesting part is this: the p- sound in Proto-Indo-European evolved into the Germanic and then English f- sound. Think about father and padre, for example or foot and pie. Five and cinco follow this pattern too, but in a more subtle way.
The Proto-Indo-European for the same, *penkwe, evolved into the Latin word for “five”: quinque. The qu- was pronounced in a hard way like a k- and then, as Latin evolved into Spanish, the k- was softened into the soft c- in cinco. So p- to k- to c-. You can see it through the similar sounds.
Indeed, the pattern is most obvious in the repetition of the sounds in both works cin-co as the c/k sound twice, at the start of each syllable. And the fi-ve as the f- sound (and its closely related, usually identical and often interchangeable sound of v-) at the start of each of its syllables as well.
The English foot comes from the Indo-European root *ped. Think pedal.
Interestingly, the “p” sound consistently transformed into an “f” in the Germanic languages — but remained a “p” in the Latinate languages.
This is why, foot is equivalent to pie.
Other examples of this pattern include father and padre, and the English far is from the same root as the Latin per.
Pluma, Spanish for “feather”, sounds nothing like the English feather.
But it is a cousin to the English fleece.
Both come from the same Indo-European root *pleus-, which meant “feather” or to “pluck.”
But they sound so different! That is because the Indo-European p- sound stayed the same into Latin then Spanish, but changed into a f- in the Germanic branch (including English).
Thus the p-l of pluma maps to the f-l of fleece.
It is both surprising and funny that in Spanish, a Flea Market is translated to be, literally, exactly the same: Mercado de Pulgas.
But it is even more surprising (although probably less funny) that flea and its Spanish translation, pulga, are close cousins – despite the different sounds.
Both derive from the Indo-European *plou. To understand this transformation, we should remember that the Indo-European p- sounds stayed the same in Latin (and thus Spanish) but became an f- sound in German (and thus English).
Therefore, the f-l of flea maps exactly to the p-l of pulga!
