Chase3SG

Chase3SG is a compact label used in some computational linguistics resources to denote the verb chase in the third-person singular present tense. It is not a standard English word or inflected form, but a metadata token that can accompany a surface form in annotated corpora or lexical databases. In typical analyses, chase3SG corresponds to a lemma of chase, part of speech verb, tense present, person third, number singular.

In annotation schemes that separate lemma, morphological features, and surface form, chase3SG can serve as a concise shorthand for the combination. The ordinary surface form for this inflection in English is chases, as in “he chases the ball.” Some datasets encode the same information using different tagsets (for example, using a feature-based scheme with tense, person, and number fields, or using a standardized tag like VBZ in Penn Treebank-style schemes).

Related labels in similar annotation schemes would include chase1SG, chase2SG, and chase3PL, often used to illustrate or organize inflectional variants alongside the base form chase. Depending on the resource, chase3SG may appear as a label in lexical entries, morphological analyzers, or generation systems, rather than as a standalone English word.

Chase3SG is most commonly encountered in data processing pipelines, educational demonstrations, or research datasets where compact, machine-readable representations of inflection are advantageous. It is less common as a descriptor in descriptive grammar, which typically relies on broader tagsets that map to standardized features.
