When to Use Informal Register
Informal English is the register of everyday life. Use it with friends, family, and colleagues you know well. It favours shorter Anglo-Saxon roots (start over commence, kid over child), contractions (don't, can't, won't), and idiomatic expressions. Informal register builds connection. Use eagerly in conversation; use carefully in writing — what reads natural in speech may read sloppy on the page.

FAQ
When should I use informal vocabulary?
Use informal vocabulary in conversation, friendly emails, social media, and personal writing. It builds rapport and sounds natural. Avoid in academic essays, cover letters, or formal complaints.
How do I know a word's register?
Each dictionary entry tags the word's register explicitly. Tap the "Open full dictionary entry" link on any card to see the register tag plus example sentences in context.
Can I mix registers in one document?
Sparingly, and on purpose. Effective writers occasionally drop in an informal word to break a long formal passage, or a formal word to add weight to casual writing. But sustained register-switching reads as inconsistent.
