heikentymis

heikentymis is a term used in some discussions of linguistics to denote the process by which the semantic strength or emotional charge of a word, phrase, or expression diminishes across use or time. The term is modeled on Finnish heikentää, meaning to weaken, and is used in English-language scholarship to describe a semantic weakening or bleaching.

In practice, heikentymis covers both diachronic change (semantic drift that reduces force over generations) and synchronic phenomena (contextual weakening in discourse). Mechanisms include semantic bleaching, dilution of intensity, and pragmatic weakening through frequent use in non-literal contexts. It is closely related to, but distinct from, broad semantic change and polysemy.

Instances frequently cited include words that accumulate attenuated meanings through frequent, non-technical use or shifts from precise to generalized senses. In corpora, occurrences of signals of strong sentiment or evaluative force may decline in formal registers while persisting in colloquial speech, illustrating heikentymis in action. Scholarly debate centers on how to define boundaries between heikentymis and ordinary lexicalization, the relative role of social factors, and methods for measuring weakening. Some researchers treat heikentymis as a descriptive label for observed patterns, while others argue it corresponds to underlying cognitive or affective processes.
