over many years, I've noticed how it's all about differences that get more subtle and precise on every field. I think this specially after watching this the introduction of https://www.youtube.com/watch?v=OMaYFUm8kQQ

this is specially complicated in fields with long histories. I've got an example that may only make sense in both english and spanish: fats, oils, gases/gasolines (grasas, aceites... gasolinas, petroleo)

other subtelties fresh on my mind today:

proposition vs axiom

argument vs parameter

(common) case law vs civil law
