Native Esperanto speakers
Native Esperanto speakers are people who learned Esperanto as one of their first languages. Esperanto is not spoken in any countries as an official language, so they must become bilingual, trilingual, or multilingual. Native Esperanto speakers can use this language completely and more fluently than non-native Esperanto speakers. There are not very many native Esperanto speakers. It is thought that no more than one or two thousand people speak Esperanto as their first language.
Children who learned Esperanto as one of their first languages speak with grammar like the other languages they learned.
