A subdomain of language: producing speech and writing. Impaired in Broca's aphasia while comprehension stays relatively intact — the classic production/comprehension split.

Commonly seen in Broca's aphasia is agrammatism, speech and writing in which the small elements of grammatical structure, typically the so-called function words such as articles, auxiliary verbs, and some…. PMC10631800

10.1016/j.nicl.2015.10.010 — The DSM-5 Neurocognitive Work Group agreed on six principal domains of cognitive function, each with subdomains. Language comprises object naming, word finding, fluency, grammar and syntax, and receptive language. Taxonomic edge, not a causal mechanism: this is a DSM-5 domain/subdomain relationship, not a pathway acting on another. Sachdev 2014, Nat Rev Neurol 10:634-642 — Classifying neurocognitive disorders: the DSM-5 approach. doi 10.1038/nrneurol.2014.181 The manual's own table pairs the two sides as 'Expressive language and receptive language' (Table 1, doi 10.1186/s13643-019-1220-4); Sachdev's figure names the receptive side only. Scope stated before anyone asks: Sachdev's Figure 2 is an ABRIDGED rendering of the DSM-5 table and does not carry every subdomain named here, so the manual's own wording is cited beside it. doi 10.1016/j.nicl.2015.10.010
