Sranan Tongo (lit. "Surinamese tongue") is an English-based creole language spoken as a lingua franca by approximately 500,000 people in Suriname. Shared between the Dutch-, Indigenous-, Javanese-, Hindustani-, and Chinese-speaking communities, Sranan Tongo generally serves as a second language, although around 125,000 Surinamese speak it as a first language. Sranan Tongo's lexicon is a fusion of English, Dutch, Portuguese and Central and West African languages, with rampant use of Dutch loanwords. Although it has no direct relatives, Sranan Tongo displays numerous similarities with Krio, the lingua franca of Sierra Leone—to the point where the two languages are somwhat mutually intelligible—as well as with Atlantic English pidgins to a lesser extent.
This language pair is the first of its kind in existence online. Although much progress has been made in lexicon and grammar, more work is needed to improve grammar in the Sranan to English direction.
One major challenge in Sranan-English translation is that many verbs may also be used as their related nouns or adjectives (and vice versa). To compound this problem, determiners (found before nouns) take very similar forms to personal pronouns (found before verbs), making it difficult to disambiguate words. For example, 'mi singi' may be translated either as 'my song' or 'I sing'; 'den aksi' may mean either 'they ask' or 'the questions.'
