Priprefix

Priprefix is a hypothetical morphological concept used in linguistics and constructed-language discussions to describe a prefix that attaches before the regular base prefix in a word. The term blends "pre-" and "prefix" and is used to capture a two-layer prefixing process in which an initial prefix can modify the entire ensuing prefixing sequence as well as the root.

In a word-formation model, a stem S can take a base prefix B to form B + S. A priprefix P would be analyzed as attaching to the stem before B, giving P + B + S. The resulting structure is thus P-B-S, a hierarchical prefix complex rather than a single, flat cluster of prefixes. The semantic effect of a priprefix is not standardized and would be language-specific; it could influence aspect, modality, negation, stance, or other grammatical categories depending on the grammar.

Natural-language attestations of priprefixes are rare or nonstandard; the concept is primarily discussed in typological theory and in conlang communities as a tool for exploring affix-order constraints and morphological productivity. Purely hypothetical examples are common in demonstrations, and researchers may employ them to test how treatments of multiple affixes interact with phonology and syntax.
