Which term describes the degree of formality of language used in a given context, such as formal versus informal situations?

• A. Register
• B. Restructuring
• C. Scaffolding
• D. Subtractive bilingualism

Answer: (A)

Register describes the degree of formality of language used in a given context. It governs how you choose words, sentence structure, and tone based on the audience and purpose—formal and technical in academic or professional settings, informal and casual in everyday conversation. In formal contexts you’ll see precise vocabulary, full sentences, and fewer slang terms; in informal settings, contractions, colloquialisms, and a relaxed tone are common. The other terms refer to different ideas: restructuring is about rearranging sentence elements, scaffolding is support for learners, and subtractive bilingualism deals with language development dynamics. So register is the term that best fits the concept of formality in context.
