Keelekesed

Keelekesed is a term used in linguistics to describe short, recurrent language units—phonetic fragments, syllables, or brief lexical elements—that appear across utterances in a speaker’s discourse. They are studied to understand how language is structured, learned, and used in context.

Etymology and scope: The word stems from Estonian roots combining "keel" (language) and a plural suffix, and it has varying definitions in literature. Some researchers treat keelekesed as phonetic seeds—small units that seed larger words or phrases—while others classify them as discourse markers or fillers.

Characteristics: Keelekesed are compact, often less than one syllable to a few syllables long. They may be phonetic, such as small sequences of sounds; or lexical; or multimodal when spoken with prosodic cues. They tend to be highly frequent within a given corpus and show cross-linguistic parallels.

Methods and contexts: Researchers identify keelekesed in corpora via frequency analysis and pattern mining, supported by manual annotation. In child language acquisition, keelekesed may function as scaffolding during early utterances. Sociolinguistic studies examine how keelekesed vary by region, register, and social group.

Significance and examples: Studying keelekesed sheds light on segmentation, fluency, and discourse organization. They relate to concepts such as lexical bundles, fillers, and discourse markers. Examples in many languages include short recurrent filler sequences or stance markers, which help speakers manage interaction.
