Every language has different registers — ways of speaking that shift depending on who you're talking to and the situation. Formal language is used with people you don't know well, in official settings, or to show respect (like speaking to a teacher or in a job interview). Informal language is more relaxed and casual, used with friends and family — it often includes slang, contractions, and shortcuts that would sound out of place in a formal setting. Many languages also have specific formal and informal words for 'you' (like French's 'tu' vs 'vous', or Spanish's 'tú' vs 'usted'), which English doesn't have — English shows formality mostly through word choice and tone instead.
Getting register right matters: using overly casual language in a formal situation can come across as disrespectful, while being overly formal with friends can feel stiff or distant.
Example
In English, you might text a friend 'hey, what's up?' but you'd greet a job interviewer with 'Good morning, thank you for having me' — same language, very different register depending on the situation and relationship.

Formality has no connection to context
9. French "tu" versus "vous" is an example of:
A formal/informal distinction in the word for "you"
Two words with identical meaning and use
A spelling mistake
A type of punctuation
10. Why might being overly formal with close friends feel odd?
It can feel stiff or distant, mismatched with a casual relationship

11. Choosing your words based on who you're speaking to and the situation demonstrates:
An awareness of register
Poor language skills
A grammar mistake
Nothing meaningful
12. A text message to a friend and a formal email to a teacher would typically differ in:
Register — formality of tone and word choice
The alphabet used
Whether words are used at all
Nothing at all
13. Why do many languages build formality directly into their grammar (like special "you" forms), while English mostly doesn't?
Languages develop different ways of expressing the same social concept of formality
All languages are grammatically identical
English has no concept of politeness
Formality is not expressed in any language
14. Recognising when to switch from casual to formal language is an example of:
Adapting your register to the situation
Ignoring your audience entirely
A translation error
Speaking a different language entirely
15. Why might a language learner who only ever practises formal, textbook phrases struggle in a casual real-world conversation?
Real conversations often use informal register, slang and contractions not covered by formal textbook language
Textbook language always matches every real situation perfectly
Formal and informal language are identical in every language
Register has no impact on real communication
16. A student uses "vous" (formal "you") to address a close friend in French. What might this choice unintentionally communicate?
A sense of distance or unusual formality, since "tu" would normally be expected between friends
Nothing at all — the choice makes no difference
That the student is being extremely casual
That the sentence is grammatically incorrect
17. Why is understanding register considered an important part of language and cultural competence, not just vocabulary?
Using the right level of formality shows social awareness and respect for the relationship and context
Register has no connection to culture
Vocabulary alone guarantees appropriate communication in any situation
Cultural competence only involves grammar rules
18. Why might register expectations differ between cultures, even for similar situations?
Different cultures can have different norms around formality, politeness and social distance
Register is identical across every culture and language
Culture has no influence on how formality is expressed
Only English has any concept of formality
19. A learner switches fluidly between formal and informal language depending on who they're speaking to. What does this suggest about their language ability?
A developing sense of pragmatic, real-world language competence beyond just vocabulary and grammar
That they are making constant mistakes
That register has no real value in fluency
That they are confused about the language
20. Why can misjudging register sometimes cause more of a communication problem than a grammar mistake?
It can affect how a listener perceives your tone, respect or intent, beyond just correctness
Register has no effect on how a message is received
Grammar mistakes are always more serious than register mistakes
Register and meaning are completely unrelated
21. Understanding formal and informal register mainly helps a language learner to:
Communicate appropriately and respectfully across different real-world situations
Ignore the situation and use the same language everywhere
