Functionally monolingual parents pass Mixtec on to children. There are 2 or 3 villages, apparently founded by outsiders, with no Mixtec speakers. In all other villages, there are Mixtec speakers, but in some, very few children learn it; in others, most of them learn it (2011). Home, friends, religion, work. All ages. Negative to neutral attitudes, but older adults want to preserve it. Some in Amoltepec center also use basic Spanish [spa], but those in outlying hamlets quite monolingual. A few know some English [eng]. Communication often carried on in 2 languages, with one speaking Mixtec and the other answering in Spanish. Many children speak Spanish more than Mixtec, though they may know Mixtec. In some communities, they no longer learn to speak Mixtec.
