A foreign language is a language that is not an official language of, nor typically spoken in, a specific country. Native speakers from that country usually need to acquire it through conscious learning, such as through language lessons at school, self-teaching, or attending language courses. A foreign language might be learned as a second language; however, there is a distinction between the two terms. A second language refers to a language that plays a significant role in the region where the speaker lives[citation needed], whether for communication, education, business, or governance. Consequently, a second language is not necessarily a foreign language.
Children who learn more than one language from birth or at a very young age are considered bilingual or multilingual. These children can be said to have two, three, or more mother tongues, meaning these languages would not be considered foreign to them, even if one language is a foreign language for the majority of people in the child's birth country. For instance, a child learning English from their English parent and Irish at school in Ireland can speak both English and Irish, but neither is a foreign language for them. This situation is common in countries like India, South Africa, or Canada, which have multiple official languages.
In general, it is believed that children have an advantage in learning foreign languages compared to adults. However, studies have shown that pre-existing knowledge of language and grammar rules, as well as a superior ability to memorize vocabulary, may benefit adults when learning foreign languages.[1][2]
