The meaning of mother tongue

Mother tongue, if it is the first language, its application ability is very important for a person's further learning process, because thinking is mostly based on mother tongue; Therefore, the mother tongue plays a central role in the education process. If you don't master your mother tongue well, it will be difficult to learn other languages. Mother tongue is not determined by birthplace or descent. Mother tongue is not necessarily the mother's language. For example, in some patriarchal societies, mothers come from different language areas, while children usually only use the local language, and only a few people can master the mother's language. Similarly, for the descendants of immigrants, "mother tongue" is not necessarily the language of the mother country or the motherland, and may even be an artificial language (such as Esperanto). A person can have two or more mother tongues, so he is bilingual or multilingual. The order of language learning does not necessarily represent proficiency.
