Wordcommitment

Wordcommitment is a theoretical construct in linguistics and psycholinguistics describing the tendency of speakers to fix, or commit to, a particular lexical item during the planning of an utterance. The concept is used to explain how early decisions about which word form to choose can influence subsequent language production, by reducing competition among alternative lemmas and forms and guiding selection toward a coherent realization.

In commonly cited models, wordcommitment occurs after conceptualization and before articulation, narrowing the set of candidate words and constraining inflection, collocation, and syntactic structure. Once a word is committed, related retrieval pathways may be primed, facilitating reuse of the same term and shaping nearby choices such as preferred modifiers or surrounding syntax.

Evidence for wordcommitment comes from psycholinguistic experiments and techniques such as priming, self-paced reading, eye-tracking, and speech onset latency. Some studies report rapid facilitation when the same word is reused, as well as reduced interference from competing lexical items. However, findings are not uniform across languages and task designs, leading to ongoing debate about its timing and universality.

Applications of the concept appear in models of natural language generation, second-language instruction, and computational speech systems, where balancing commitment with flexibility affects fluency and predictability. Critics argue that wordcommitment can be difficult to distinguish from general lexical access efficiency or strategy effects, and that operational definitions vary, making empirical consensus challenging.

Related concepts include lexical entrainment, incremental planning, and lexical access in production models. See also lexical decision, priming, and language production theory.
