Explanation
Register shift is a change in linguistic choices relative to situation, activity or audience. Vocabulary, syntax, pronunciation and address forms may contribute. A shift need not move between two sharply bounded packages; individual features may change gradually. In the code-switching context, analysis must separate a change of language or variety from a change of register. They can coincide but need not. Registers also do not occupy one fixed scale from better to worse. Appropriateness depends on communicative purpose and participants.
Movement of thought
1. Describe the initial situation. 2. Record changing linguistic features. 3. Compare address and activity. 4. Test language switching and register shift separately. 5. Infer effects from responses.
Scientific use case
Sociolinguistic research can compare feature clusters and situational changes across stretches of discourse.
Example
Someone explains a process first to specialist colleagues and then to a child. The language may remain the same while terminology, syntax and assumed knowledge change.
Counterexample
A brief foreign proper name does not automatically constitute a register shift.
Distinction
Distinguish register shift from language switching, accent alone, fixed social identity and a scale of language quality.
Effect on thought and perception
Register shift reveals adaptation to different communicative tasks.
Resonance
A voice remains recognisable while changing its distance from the listener.
