What is register-shift?

• A. A shift in tense; from past to present.
• B. A shift in point of view; from first person to third person.
• C. A shift in formality; e.g., from "we shall commence" to "we'll start" when moving to dialogue with friends.
• D. A shift in sentence length; from short to long.

Answer: (C)

Register-shift is changing the level of formality in language to fit the audience or situation. It’s about moving from more formal wording to more casual, or vice versa, within the same text or conversation. In the example, shifting from “we shall commence” to “we’ll start” signals a move from formal diction to casual speech when talking to friends. This helps convey the right tone and relationship with the listener. The other ideas describe different changes—changing tense is about timing (past vs. present), changing point of view is about who is narrating, and altering sentence length affects pacing, not the formality level.
