Loppualku

Loppualku is a neologism used in speculative linguistics and literary theory to describe a class of boundary-linked linguistic and narrative phenomena. It denotes a continuity across the boundary between units—such as words, clauses, or scenes—where features at the end of one unit link with features at the start of the next, creating a sense of seamless flow.

Etymology: The term is formed from Finnish loppu meaning end and alku meaning beginning. It has no formal status in established linguistics and is used principally in informal discussions, experimental writing circles, and some online theories to discuss cross-boundary cohesion.

In linguistic practice, loppualku can refer to two related ideas: a phonological or morpho-phonemic linkage across unit boundaries, such as shared final and initial segments; and a narrative device in which the ending of one segment motivates or dictates the opening of the next, producing a cyclical or continuous reading experience. In digital media and design, it has been used to describe interfaces that emphasize transition by overlapping cues or by continuing a motif from one module to the next.

Reception: Because it lacks a single accepted definition, usage varies by author and field. Some see it as a useful shorthand for cross-boundary cohesion; others view it as a loose metaphor rather than a technical term. It remains primarily within speculative or experimental contexts rather than mainstream linguistic theory.
