If there’s one thing I love about travel, it’s when a place has a story hidden in its name. Peru’s Lake Titicaca and its islands are perfect examples — their names reveal layers of language, history, and culture that stretch back centuries. And before you get too excited, “Titicaca” has nothing to do with mammary glands and the Island of Taquile has nothing to do with the drink.
Let’s start with Lake Titicaca itself.
The name is believed to come from the Aymara language, and it might mean either “Rock Puma” or “Gray Puma.” In Aymara, titi means puma and caca means rock (or sometimes gray). Some say it refers to the shape of the lake, which local traditions describe as resembling a puma hunting a rabbit (though I think it looks more like a fox chasing a squirrel). Others link it to a sacred rock on Isla del Sol carved in the likeness of a puma.

Either way, the name isn’t just poetic. The puma was one of the three sacred animals in Andean mythology, symbolizing strength, vitality, and the earthly world, alongside the condor and the serpent. Some historians even suggest that “Titicaca” evolved from Thaksi Cala, the ancient name for that sacred rock, slowly reshaped by centuries of translation and mispronunciation.
As for Taquile Island…
This is another cultural gem on Lake Titicaca. The Spanish gave it its modern name, derived from the Gonzalez de Taquila family, who once owned the island after the Inca Empire’s fall. But long before the Spanish arrived, the island was known by its Quechua name: Intika. The two names tell a story of Peru’s layered history. One Indigenous, one colonial – both still alive today in the culture and language of its people.
And finally the Floating Islands of Uros
The Uros people, who built and live on these reed islands, primarily speak Aymara and Spanish today. Their original language, Uru, has nearly disappeared, though efforts to revive it continue. The name “Uros” itself is thought to come from Quechua, meaning either “people” or “bird.” However, they call themselves Kostuña, meaning “the lake town.” Even in name, their identity reflects resilience and adaptation – a culture floating, quite literally, between past and present.
So next time you hear “Lake Titicaca,” you’ll know it’s more than just a dirty sounding name to say. It’s a linguistic time capsule, filled with stories of pumas, sacred rocks, and people who’ve called this high-altitude lake home for thousands of years.
