prefixlingua

Prefixlingua is a hypothetical constructed language concept in which most grammatical information is expressed through prefixes attached to lexical roots. The design emphasizes prefix-based morphology over inflection on stems or reliance on separate function words, producing a modular system where meaning is built by stacking prefixes.

Its prefix inventory includes classes for person and number on verbs, tense and aspect on tense markers, mood and voice, and case and definiteness on nouns, with evidentiality and mood markers available as optional layers. Prefix order is fixed, with each layer contributing a distinct grammatical value; roots themselves are minimally inflected. This arrangement supports an agglutinative feel, where long prefix strings, rather than suffixes, carry complexity.

Syntax is relatively flexible because the morphology marks subject, object, and other relations. The language often defaults to a subject–verb–object word order, but variations are common when discourse focus or emphasis demands it. Function words are minimized, and information structure tends to be carried by the prefix chain rather than separate particles.

Examples: pa-lex means “speaks,” with pa marking present tense and lex as the root “to speak.” no-lex means “spoke,” with no- marking past tense. These examples illustrate how prefixes encode tense and other grammatical relations directly on the verb root.

Origins and reception: The concept appears in academic and hobbyist discussions of morphology and conlang design as a thought experiment illustrating the potential of prefix-only inflection. Proponents argue it clarifies grammatical function and can aid computational parsing, while critics note potential cognitive load from long prefix sequences and possible ambiguity when prefixes interact.
