Formësuopostfix

Formësuopostfix is a theoretical construct used in linguistic morphology and data-processing linguistics to describe a postfix morpheme chaining mechanism. It defines how a base form can be extended by attaching a fixed sequence of suffix morphemes in a prescribed order to yield a derived form. The term blends form and postfix, and orthographic accents are sometimes used to mark its status as a specialized, non-standard construct.

Mechanism: When given a base form B and a predefined sequence of suffixes [s1, s2, ..., sn], the formësuopostfix operation produces Bs1s2...sn. Each suffix encodes a linguistic feature (such as tense, number, or mood) or a discourse function in a data-encoding context. The order must be fixed for consistent interpretation, and interactions between adjacent suffixes may trigger morphophonemic adjustments or allomorphy.

Examples: In a hypothetical language, a base form lake followed by the sequence [-pl], [-past], [-def] yields lake-pl-past-def. In a programming-inspired variant, the same base could receive an informational sequence [meta], [ver] to produce lake-meta-ver. These demonstrations illustrate how formësuopostfix operates as a deterministic suffix-chain operator.

Applications and relation: The concept is used in formal linguistics to model suffix stacking and in natural language processing pipelines to describe deterministic morphology steps. It is related to, but distinct from, general postfix notation and from concatenative morphology, as it emphasizes a fixed, semantically interpretable sequence of suffixes rather than arbitrary concatenation.
