The Spanish aprovecharse (“to take advantage of,” in a good way) comes from the Latin ad– (“towards”) and profectus (“progress, success.”)

From the same root profectus, we get the English… profit.

We can see the root pr-v of aprovecharse mapping to the pr-f of profit. And how do you make a profit if not by taking advantage of the opportunities in front of you?

Seguir, Spanish meaning “to follow”, sounds like it has nothing to do with anything.

But it does, in a subtle way. It comes from the Latin sequi, which means “to follow.” From the same root we get:

• Persecute – from the Latin persequi; the per means “through”, and the sequi is the same “follow”.
• Sequel – directly from the Latin sequi for “follow”, via French.

Haber (“to have”, in the grammatical sense, and the root form of he, has, ha, hemos, etc) comes from the Latin for habere, meaning “to hold.”

From the same root, we get the English word habit. What is a habit if not something you hold so dearly that you do it all the time? We also get prohibit (the same root with the prefix pro meaning “away”). What is a prohibition if not a habit that you’re trying to stop?

The h-b root is so obvious in all, it’s almost not worth mentioning. Almost!

Both the Spanish nieve and the English for the same, snow, come from the same root, although via very different routes.

In Proto-Indo-European, the ancient ancestor to both Spanish (PIE turned into Latin then Spanish) and English (PIE also turned into ancient Germanic then English), the Proto-Indo-European *sniegwh for snow gave rise to both the Latin nivis — which turned into the Spanish nieve — and the old German sneo which became the English snow.

Thus, the n-v of nieve maps exactly to the n-w of snow. The key sound change, which is what can confuse us, is the loss of the initial s- as the word transformed from PIE into Latin and then Spanish.
