Synthequa

Synthequa is a constructed language (conlang) designed to study morphosyntactic systems and to provide a neutral medium for international artificial communication. It emphasizes regular morphology and a flexible, case-marked syntax intended to support both human learning and machine processing.

Development of Synthequa began in 2012 under linguist Dr. Elena Korsen and a collaborative team at the Synthequa Institute. The project aimed to combine agglutinative morphology with a compact root lexicon, enabling productive word formation while remaining approachable for learners. Public descriptions appeared from 2014 onward, with ongoing updates to grammars and corpora released as open resources.

Phonology and writing: Synthequa uses a Latin-based alphabet with a phonemic inventory designed for clarity. It has five vowel phonemes and eighteen consonants, no phonemic tone, and stress typically on the penultimate syllable. The orthography is largely phonemic and includes common digraphs such as sh and ng.

Grammar and syntax: The language is predominantly agglutinative with regular affixes. Nouns inflect for case (nominative, accusative, dative) and number; determiners are optional. Adjectives generally follow nouns. Verbs inflect for tense (past, present, future) and aspect, with person agreement on the verb. Word order is relatively flexible due to case marking, though the canonical order is subject–verb–object. Prepositions are minimized, with function carried by postposed case markers when needed.

Lexicon and usage: The core vocabulary comprises about 2,000 root words, with productive affixes for derivation. Synthequa is used in academic demonstrations, online learning communities, and fictional-world media, with open-source grammars and lexicons maintained by its user community.
