grammatikalisches

Grammatikalisches is the neuter singular form of the German adjective grammatikalisch, meaning “grammatical” or “pertaining to grammar.” In German, adjectives decline to reflect gender, number, and case, and grammatikalisch appears in its various inflected forms as part of attributive phrases or predicatives.

In attribute position, the ending of grammatikalisch depends on the determiner and the case. With an indefinite article or no determiner, the neuter singular form is grammatikalisches, as in ein grammatikalisches Problem or ein grammatikalisches Phänomen. With a definite article or a demonstrative determiner, the form shifts to grammatikalische in neuter singular, as in das grammatikalische System or dieses grammatikalische Phänomen.

Grammatikalisches can also appear in predicative position, typically in constructions where the adjective describes a noun of neuter gender, though in many contexts the predicate form resembles the stem with a suitable ending for the sentence (for example in longer clauses stating that something is grammatical).

Nominalized use is possible and common in academic or theoretical writing: das Grammatikalische (capitalized), referring to the concept of grammar itself rather than a specific grammatical item. This nominalization follows standard German rules for capitalizing adjectives used as nouns.

Etymology and relation to broader terminology: grammatikalisch derives from Grammatik (grammar) plus the adjective-forming suffix -al and the standard adjectival ending -isch, with further declension in full sentences. The term is primarily a grammatical descriptor rather than a lexical item with independent meaning.
