Idiomin

Idiomin is a term used in linguistics to denote a particular subclass of idiomatic expressions characterized by fixed form, non-derivational structure, and a high degree of cross-linguistic stability. In this framework, an idiomin behaves like a single unit in discourse, carrying a figurative meaning that is not directly inferable from its individual components and showing limited variation in wording and syntax.

Etymology and history: The term idiomin was coined by linguist Dr. Mina Arai in the early 2010s, combining idiom with the suffix -min to indicate a minimal, fixed expression. Since then, it has been employed in cross-linguistic studies of phraseology and in computational linguistics to differentiate highly stable expressions from more productive multiword units.

Definition and characteristics: An idiomin typically consists of two to four words and exhibits non-compositional semantics, meaning its meaning cannot be deduced from the meanings of its parts. It also tends to maintain a stable word order across sentences and shows limited permissible modification. While idioms in general can vary by language, idiomin-like expressions often show parallel patterns in related languages, allowing researchers to identify cross-linguistic correspondences.

Applications: In corpus linguistics and natural language processing, identifying idiomins can improve machine translation, sentiment analysis, and lexicographic work by enabling systems to treat these expressions as single semantic units. Annotated corpora focusing on idiomins help lexicographers and language resources capture the fixed, figurative nature of these expressions.
