Bolivian Spanish word
la ch'alla
Meaning: the ch'alla (an Andean blessing / offering custom)
How it is used in Bolivia
A widespread Andean custom of blessing and giving thanks, what exactly it means and how it's done is something you ask about and hear from those who practise it, never something to declare or turn into a show. Around Copacabana you'll see it in the weekend blessing of vehicles.
