The Nerdy Way To Learn: Spanish » Patterns » F to P »

Pegar and Pituitary and Fat

The Spanish pegar (“to paste”) comes from the Latin pix, meaning “tar.” That makes sense: “paste” looks like just a more diluated “tar.”

But pix itself comes from the Proto-Indo-European root pei(e), which meant, fat — think of animal fat, for example. It makes sense that this word evolved into a word meaning “tar”: that’s a bit what animal fat looks like.

From this same root pei(e), we get a few notable English words:

  • Fat — Fat itself comes from this root! This is through the PIE p- sound transforming into the f- sound as it evolved into German and English. Think about father/padre, for example.
  • Pituitary — The same root came back in, via an educated Latin, to mean, the pituitary gland. Why? Because the ancients believed that this slimy gland is what produced mucous/snot — the smile of the nose. A bit like tar, isn’t it? We can see the P- root preserved here, too.

Espuma and Foam

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!

Pluma and Fleece

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.
