Which of the following is NOT a factor related to loss of the first language (L1)?

A supportive bilingual family plays a crucial role in maintaining the first language (L1). In such families, both languages are often spoken, which creates an environment conducive to L1 retention. Children who grow up in a bilingual setting where both languages are encouraged are less likely to lose proficiency in their L1.

Conversely, engagement with monolingual speakers tends to promote the use of a second language (L2) at the expense of L1. Limited interaction with peers who speak L1 can lead to diminished practice and use of that language, further contributing to language attrition. Having parents who are bilingual provides additional opportunities for children to use and develop their L1 as both parents can model and maintain language usage.

In summary, a supportive bilingual family fosters language development, making it a protective factor against loss of L1, rather than a contributing factor.
