Here’s where it gets interesting: the Latin words beginning with f- generally turned into the silent h- in Spanish but not in the other Romantic languages, and thus hierro (from the Latin ferrum) is related to:
Ferrocarril — Spanish for railroad. It maps almost perfectly to the English: ferro for ferrum, “iron”; and carril for road, way, or path (think of the common Spanish word for path or way, carrera).
Ferrari — the luxury sportscar from Italy, is named after their founding family’s last name. And that last name, in Italian, originally meant… iron-worker.
Nerds love to pattern-match, to find commonalities among everything. Our approach to learning languages revolves (the same -volve- that is in "volver", to "return") around connecting the Spanish words to the related English words via their common etymologies - to find the linguistic patterns, because these patterns become easy triggers to remember what words mean.
