leksemide

A leksemide is a conceptual unit of meaning in linguistics, distinct from a word in its flexibility and ability to represent a core meaning that can be expressed by various word forms. It is considered a more abstract entity than a lexeme, which is the set of all inflected forms of a single word. For example, the leksemide "run" encompasses the meanings conveyed by "run," "runs," "ran," and "running." The concept helps linguists analyze how a fundamental idea is realized through different grammatical structures.

The term leksemide is used in some theoretical frameworks to differentiate between the abstract semantic content and its surface-level phonetic or orthographic representations. This distinction is useful in fields like computational linguistics and natural language processing, where understanding the underlying meaning independent of specific word choices is crucial. It allows for more robust analysis of texts and speech, enabling systems to recognize the same concept even when expressed differently. For instance, a search engine might use the leksemide concept to identify all documents related to the act of "running," regardless of whether the word "run," "ran," or "running" is used. The study of leksemides contributes to a deeper understanding of linguistic variation and the relationship between semantics and morphology.
