Historical Police Motu / Hiri Motu — ANLHE Historical Language Encyclopedia and 90-Lesson Guide
Learn about the language through original historical grammar books, source-based lexical studies, writing conventions, community institutions and the history of its documentation. This entry provides a scholarly overview and ninety individually titled source-oriented learning objectives.
1. Classification, region and historically written evidence
Hiri Motu is a Motu-lexified historical lingua franca developed in Papua New Guinea. Formerly called Police Motu, it is distinct from the fully developed native Motu language and should not be presented as an inherited separate Austronesian branch. A simplified contact variety arose through trade and multilingual interaction near Port Moresby and became institutionalized through the Armed Native Constabulary after 1890. The title Police Motu remained common until the early 1970s, when Hiri Motu became the preferred name. Percy Chatterton’s Hiri Motu (Police Motu) appeared in 1971. Thomas E. Dutton’s Police Motu: Iena Sivarai (1985) offers a 159-page historical analysis. ANU Archives collection AU ANUA 314-69 includes 1970–1982 printed materials and official publications in the contact language. Distinguish precolonial social history from the date of the surviving dictionary, manuscript, printed grammar or archive. A language may have been spoken long before written documentation.
2. Script and original sound notation
Roman writing from Motu-derived conventions, including official printed Police Motu and Hiri Motu texts. The term hiri refers to Motu traditional trading voyages, but the pidgin language’s history should not be conflated with an unchanged precolonial trade language. Reproduce historical transcriptions accurately from the source edition. European writers’ old orthographic conventions may not represent current phonological analyses, while modern normalized transcriptions must be labelled clearly.
3. Original language structures and grammar
Reduced inflection and lexical restructuring compared with full native Motu, pronoun and possessive variants, particles, vocabulary influenced by neighboring Papuan and other languages and differences between Central and non-Central contact varieties. When analyzing vocabulary or an actual original-language sentence, identify lexical root, person reference, noun phrase, possessive marker, verbal morphology and word-order effects directly from an attested passage. Do not transfer grammatical rules uncritically from another Papua New Guinea language.
4. Named primary source and verifiable examples
Chatterton, Hiri Motu (Police Motu) (1971); Dutton, Police Motu: Iena Sivarai (1985); ANU Archives AU ANUA 314-69 includes Police/Hiri Motu governmental and biblical texts from 1970–1982.
These items identify real printed works, archive locations and research witnesses. Do not treat a publication title as an original sentence, and do not invent supposedly ancient inscriptions or unattested historical dialogue.
5. Original paragraph and inscription reading method
Locate an authentic printed grammar passage, official communication or archived text, record full bibliographic information and original page, and copy its period spelling. Identify source-language versus translated text, segment words and grammatical markers, give a cautious word-by-word gloss, compare later analytical scholarship and note historical regional variation.
6. Social, political and language-contact history
Document trade routes, mission schools, community knowledge, customary institutions and language contact without assuming the missionary written variety was the only local speech. Police Motu arose as a multilingual lingua franca, Yabem was promoted as an Oceanic school language, and Kâte represents a separate non-Austronesian linguistic tradition.
7. Reliability of historical linguistic claims
Do not conflate full Motu and Hiri Motu, present a late grammar printing as the language’s origin, confuse the first and third editions of Lawes, or classify Kâte as Oceanic. Identify exact historic author, publication date, original script and geographical variety before interpreting any direct quotation.
