formssometimes

formssometimes is a term used in linguistic discussions to describe a morphosyntactic phenomenon in which a particular word form is realized only in some contexts, while in other contexts a different form is used or the form is omitted. It is a coined label rather than a standard category, employed to describe intermittent or context-driven variation in inflection, cliticization, or derivation.

Usage and scope: The concept captures variability across registers, dialects, discourse conditions, or historical change. Triggers can include formality level, emphasis, syntactic position, or prosody. formssometimes is related to but distinct from allomorphy, zero morphology, and cliticization; it emphasizes intermittence rather than fixed alternations across all contexts.

Patterns and examples: In some languages, a form may appear only in subordinate clauses or in formal documents; or a cliticized form occurs only when attached to a pronoun. In another pattern, a verbal or nominal form may be marked in narrative discourse but unmarked in direct speech. These patterns are usually described with context-sensitive rules rather than universal prescriptions.
