What is Register Variation and Code-Switching?

Register and code-switching are ways speakers adapt their language to fit the context and audience. Register is the formality level and style of speech (formal, informal, neutral), while code-switching is the practice of mixing two or more languages in the same utterance.

Short answer

Register is your level of formality and vocabulary choice (vous vs. tu, bonsoir vs. salut); code-switching is alternating between languages (speaking French and English in one sentence).

Register Levels in French
Formal Register
  • Addressing strangers or authority
  • Professional or official contexts
  • Vous form, polite phrases
  • 'Bonjour, comment allez-vous?'
Informal Register
  • Friends or family
  • Casual social settings
  • Tu form, slang, contractions
  • 'Salut, ça va?'

Step-by-step worked examples

You're in a job interview. What register do you use?

Formal register: Vous, complete sentences, standard pronunciation.
Example: 'Bonjour, je serais très honoré de travailler pour votre entreprise.'
Avoid: Tu, slang, casual phrases.

Texting your French friend — what register?

Informal register: Tu, abbreviations, emojis, colloquial language.
Example: 'Salut! Ça va? Tu fais quoi ce soir? 😊'
No formality needed.

Bilingual code-switching example: 'Je vais to the store parce que I need quelques things.'

Speaker alternates between French and English naturally.
Reason: Mixed family/friend group, or the English phrase is more common in that context.
This is normal in multilingual communities, not a mistake.
