chemischer

Chemischer is the attributive form of the German adjective chemisch, meaning chemical. It is used to describe nouns related to chemistry, substances, processes, and properties. In German, adjectives preceding nouns are declined to reflect gender, number, and case; chemischer is the masculine singular nominative form when there is no definite determiner, and it also occurs with the indefinite article, as in ein chemischer Prozess. For other cases or for feminine and neuter nouns, different endings apply (for example chemische Substanz, chemisches Element).

Typical usage includes phrases such as ein chemischer Prozess and chemischer Stoffwechsel. The form chemischer appears most prominently in contexts where the noun is masculine and there is no definite determiner, or in headlines and labels where a short form is preferred. With definite articles, other endings are used (der chemische Prozess; die chemische Substanz), and in the neuter or feminine domains different endings are applied (das chemische Element, die chemische Reaktion).

Etymology and relation to other forms: chemisch derives from the noun Chemie, which in turn comes from the French chimie and the Latin chemia, rooted in the Greek khēmeía meaning alchemy. The suffix -isch is a productive German adjective ending that turns a noun into a descriptive adjective. The term chemischer, like other inflected forms of chemisch, is a standard part of scientific and educational German, appearing in technical writing, textbooks, and industry usage to indicate a relation to chemistry.
