Translating into this locale
Lao is a tonal language written in the Lao script (left to right, no spaces between words), closely related to Thai. See Locale Lo La. This guidance is lower-confidence; have a native reviewer check it.
Translate ideas, not words.
- Lao drops subjects and pronouns when the context is clear; address people by title, name, or kinship term instead of a direct "you".
- Modifiers follow the noun. English noun stacks must be reversed.
- Lao has no inflection; time, plural, and number are shown by words and classifiers.
- Do not copy Thai vocabulary or spelling; Lao has its own words and spelling.
Register.
- Lao has polite and informal pronouns ("ເຈົ້າ" is general "you", "ທ່ານ" is formal). Use the formal forms and polite particles in public text.
- Official language in government and education follows the Lao standard; foreign terms are often adapted from Pali, Sanskrit, or French and English.
Orthography and typography.
- There are no spaces between words; spaces mark phrase or sentence boundaries. Use a Lao-aware line breaker.
- Tone marks and vowels must be in correct Unicode order.
- Lao digits (໐ to ໙) and Arabic digits both appear; Arabic digits are common in UI. Currency: kip (₭ or ກີບ).
- Dates may show the Buddhist Era in addition to the Gregorian year.
Common pitfalls
- Copying Thai spelling or vocabulary.
- Inserting word spaces.
- Using the wrong register for the audience.
