The bus — the Caribbean and Canarian word for the thing the official signs call an ómnibus.

What It Actually Means
La guagua is the bus. Not a minibus, not a coach — the ordinary urban bus, articulated and crowded, that most of Havana travels on. The state’s own signage says ómnibus and nobody has ever said it out loud. The word is shared across a specific stretch of the Spanish-speaking world: Cuba, the Dominican Republic, Puerto Rico and the Canary Islands all say guagua, which is one of the tidier pieces of evidence for how much Canarian migration shaped Caribbean Spanish. In Cuba it also survives in de guagua, meaning free of charge — getting something the way you get a ride you did not pay for.
Where It Comes From
Disputed, and the most popular explanation is the least likely. The story that it comes from an American bus company called “Wa & Wa Co. Inc.” is folklore of the neatest kind and has no documentary support. Serious candidates include a derivation from English wagon, and an older Antillean usage meaning a trifle or a thing of no cost — which would make the transport sense the borrowed one, not the original. Whether the word crossed from the Canaries to the Caribbean or the other way is likewise unsettled.
How Natives Use It
Constantly and without a second thought: coger la guagua, perder la guagua, la guagua está llena, la parada de la guagua. Note coger — in Cuba it is the ordinary verb for catching a bus, with none of the vulgarity that makes Mexicans and Argentines reach for tomar or agarrar. When no guagua comes, the alternative is la máquina, the shared American car that runs a fixed route for a fixed fare.
Common Pitfall
The clash worth memorising: in Ecuador, Peru, Bolivia, Chile and northwest Argentina, la guagua (or wawa) is a baby, from Quechua wawa — a completely separate word that happens to look the same. Voy a coger la guagua means “I’m getting the bus” in Havana and something alarming in Quito, where you would say voy a coger el bus. It has nothing to do with the Caribbean word; they simply collided. See the Ecuador hub for the Andean side of the coincidence.
