In southern South America, including Chile, avocado is called palta. In Chile they also call "palta" the mixture they make that looks somewhat similar to guacamole, but the two mixtures are different. Avocado, in Chile, is mixed simply with lemon juice, salt, and salad oil. Guacamole is avocado mixed with garlic, tomato, a little jalapeno pepper, salt, and lime juice (though that can vary, a little). Palta and guacamole are not interchangeable in my opinion!

Chilean palta, all by itself on bread, is also delicioius, and is a common treat for the afternoon/evening onces.

I stumbled upon this blog earlier today. The descriptions of the Chilean sandwiches are making me even more eager for my return trip to Chile in July!
