Which group of speakers is characterized by using English as one of their official languages?

The group of speakers characterized by using English as one of their official languages is ESL speakers, or English as a Second Language speakers. This group typically includes individuals who learn and use English in environments where it is recognized as an official language, often in multilingual nations. In these settings, English may be used in government, education, and media, allowing ESL speakers to acquire the language through formal instruction and practical use in their communities.

The rationale for this answer lies in the recognition of English as a formal mode of communication in the societal framework of these speakers, differentiating them from other groups where English may not hold official status. For example, ENL (English as a Native Language) speakers are those for whom English is their first and primary language, while EFL (English as a Foreign Language) speakers typically learn English in a context where it is not an official or commonly used language. Ethnolect speakers might refers to dialects or varieties of English used within specific ethnic communities but doesn't pertain to the official status of the language in society.
