What does Language Dominance refer to?

Language dominance refers to the measurement of the degree of bilingualism, particularly how proficient a person is in each of the languages they speak. It recognizes that individuals who are bilingual may not have equal proficiency in both languages and may have a dominant language in which they are more fluent or comfortable. This concept is crucial for understanding how bilingual individuals navigate their language use in different contexts, as it influences their communication preferences and cognitive processing.

The concept of language dominance considers various factors, including frequency of use, exposure, and proficiency levels in each language. This is particularly important in educational settings, where understanding a student's language dominance can inform instructional strategies that support their learning effectively.

In contrast, the other options focus on different aspects of language ability but do not capture the nuance of dominance. For example, the notion of having the exclusive ability to speak one language suggests a monolingual perspective that does not reflect the realities of many bilingual individuals. Similarly, evaluating vocabulary size or assessing learning pace pertains to specific skills rather than a comprehensive measure of language proficiency or dominance across languages.
