Translate ideas, not words.

  • Lithuanian is highly inflected, with seven cases and two genders. Restructure English sentences; do not translate word for word.
  • Lithuanian prefers verbs and participles. English noun stacks become genitive chains or compounds.
  • Re-express idioms by meaning.

Grammar that trips translators.

  • Plurals: one, few, many (decimals), and other categories (1 failas, 2 failai, 10 failų, 21 failas). Numerals 10 to 19 and tens take the genitive plural. See Unicode Messageformat.
  • Names are declined and take gender-marked endings (Jonas, Jono; women's surnames in -ienė, -aitė, -ytė); collect and show the gender-correct form.
  • Adjectives and participles agree with nouns in gender, number, and case; verbs agree in person and number.

Register.

  • Tu (informal) and jūs (polite or plural). UI, banking, and public text use jūs; consumer brands may use tu. Do not mix.
  • UI commands use the imperative (Įrašykite with jūs, Įrašyk with tu) or the infinitive.

Orthography and typography.

  • Use all Lithuanian diacritics; never replace them with ASCII.
  • Quotation marks „…“; dates 2026 m. spalio 17 d. (year, month in the genitive, day); decimal comma; non-breaking space for thousands; currency 12,50 €; 24-hour clock.
  • Month and day names are lowercase.

Common pitfalls

  • Dropping diacritics.
  • Wrong numeral-noun agreement.
  • Not declining names or showing the wrong gender suffix.
  • Mixing tu and jūs.
