teōcalli

Teocalli sounds grander than it is. In Nahuatl, teōcalli simply means "god-house," from teōtl, "god," and calli, "house," the ordinary compound used for temple structures in central Mexico before and during the early colonial period. The architecture was monumental. The word was plain.

Spanish chroniclers described these temple-pyramids constantly, but often through paraphrase rather than stable adoption. Later antiquarian and archaeological English preferred teocalli because the local term was cleaner than any vague phrase like "Mexican pyramid temple." The borrowing is a small act of respect. It also admits precision.

The word circulated in learned English from the eighteenth and nineteenth centuries, especially in histories of the Mexica and in museum writing. It never became everyday vocabulary, because the thing itself was never everyday for English speakers. Still, it endured. Some words stay rare because they stay exact.

Today teocalli belongs to archaeology, art history, and the language of Mesoamerican religion. It names a structure where polity, ritual, and spectacle met in stone. The compound remains startlingly direct. The gods lived in a house.
