What is primary language?

A primary language is the language that a person has spoken since they were young and is most fluent in. It is the language that they are most comfortable communicating in and typically use for everyday conversations, reading, and writing. Primary languages are often learned naturally from family members, caregivers, and communities where the individual grows up. It is the dominant language that shapes a person's thoughts, emotions, and cultural identity. Primary languages can vary greatly depending on a person's background, upbringing, and geographical location. Learning and speaking a primary language is essential for cognitive development, social interaction, and self-expression.
