What is Register?
Register is how formal or casual your language is — the difference between 'Good evening, might I trouble you…' and 'hey, quick thing'. Every language has registers; some grammar-encode them, like Japanese politeness levels, Korean speech styles, or the tu/vous and du/Sie choices of Europe.
Register errors are social, not grammatical: textbook-formal speech at a party reads as stiff, casual speech in a meeting as rude. Learners are usually taught one register (polite-neutral) and then discover natives operate across several.
The formality machinery differs wildly: French and German pack it into pronouns, Japanese into verb endings and vocabulary, English into phrasing and hedging. Knowing WHICH register a situation wants is as much a skill as producing it.
What it means for your speaking
Register is learned by using it in context — a role-played job interview and a role-played bar chat train different muscles. Varied conversation scenarios are register practice disguised as fun.
