What does grammaticality mean?
Grammaticality is the quality of a sentence or other linguistic construction being formed according to the rules of grammar. It is especially important in linguistics, where grammaticality can refer narrowly to syntactic well-formedness: whether the elements of a construction are arranged and combined in an appropriate grammatical form. The term is not identical to acceptability. A construction may be grammatical but still awkward, overly formal, contextually inappropriate, or unlikely to be used by speakers, while an informal expression may be acceptable even if it departs from a more formal grammatical pattern. Discussion of grammaticality is therefore central to questions about syntax, language acquisition, grammatical description, and judgments about correct usage. For general readers, “grammatical correctness” usually conveys much of the same idea in less technical language.
nounThe quality or state of being grammatical, especially of a sentence or construction conforming to the rules and patterns of a language. In linguistics, it may specifically refer to a construction's syntactic well-formedness.
- The degree to which a sentence or other linguistic construction conforms to the grammatical rules of a language.
"The sentence is easy to understand, even where its grammaticality is open to debate."
"The study compares several theories of how children acquire grammaticality in their first language."
"Although the version is highly compressed, its grammaticality is unobjectionable."
The plural is uncommon in ordinary writing but may occur in scholarly discussion when different degrees or types of grammaticality are being compared.
"The study compares the grammaticalities of several closely related dialects."
Grammaticality asks a deceptively simple question: can the language be built right? Even when it can, humans may still dislike how it sounds.

Where does grammaticality come from?
Grammaticality was formed in English by adding the suffix -ity to grammatical. Grammatical in turn comes from grammar, which was borrowed through Latin from Greek grāmatikē, associated with gramma, “letter” or “writing.” The same root underlies cognates and related formations such as grammatically and grammaticalization.
How grammaticality is actually used
Common in academic linguistics and language teaching. In general discussion it can sound formal or technical, though the shorter phrase “grammatical correctness” is often more accessible.
Easily confused with grammaticality
Grammaticality concerns whether a construction conforms to grammatical rules, whereas acceptability also depends on whether speakers regard it as appropriate, natural, or suitable in context.
Grammaticality concerns the structural correctness of language, while coherence concerns how ideas and propositions fit together meaningfully.
