## Translating into this locale

Apply [[locale-en-001]] and use these Trinidad and Tobago conventions. Written standard English follows British spelling, while Trinidadian and Tobagonian English Creoles are different spoken varieties.

- **Spelling:** British forms (-ise, -our, -re).
- **Dates and numbers:** day/month/year, TT$ for the Trinidad and Tobago dollar where clarity is needed, decimal point and comma thousands separator.
- **Usage:** keep local terms for food, festivals, and places (Carnival, doubles, roti) in their usual spellings; do not respell creole forms in standard copy.

## Common pitfalls

- Using US spellings or dates in official local material.
- Using creole spellings for effect in formal text.
