hacer

"To do" or "to make" — and, like French faire, the verb behind weather expressions (hace calor, "it's hot") and many idioms where English reaches for something else entirely, including hace + time ("ago": hace dos años, "two years ago").

• ¿Qué haces? — What are you doing?
• Hace mucho calor hoy. — It's very hot today.
• Vivo aquí hace tres años. — I've lived here for three years.

Trying to translate weather word for word ("it makes hot") instead of learning hace + noun as a fixed pattern, and missing that hace also does double duty as "ago"/"for [time]" in a completely unrelated construction.

• quote "Se hace camino al andar" — From Antonio Machado's "Proverbios y cantares" (in Campos de Castilla, 1912) — "Caminante, no hay camino, se hace camino al andar" ("Traveler, there is no path, the path is made by walking"). Joan Manuel Serrat set it to music on his 1969 album Dedicado a Antonio Machado, as the song "Cantares."
• expression Hecho en México — The official Mexican "Made in Mexico" mark, formalized under the NMX-Z-009-1978 standard, used to identify domestically manufactured goods and signal national pride in their craftsmanship and origin.
