What does catalytical mean?
Catalytical is an adjective meaning relating to catalysis or to the action of a catalyst. In chemistry, a catalyst is a substance that facilitates a chemical reaction while being regenerated rather than consumed, so catalytical may describe the action, process, or effect involved. The word occurs chiefly in specialized scientific writing, formal prose, and older English, where its Latinate appearance gives it a technical character. It remains a recognized English adjective and should not be treated as an incorrect form, but it is much less frequent than catalytic, the standard modern alternative. Catalytical is especially likely to appear in descriptions of catalytical action or in historical discussions of chemical terminology. For most contemporary uses, including academic and explanatory writing, catalytic will usually sound more natural, while catalytical is useful when an older, more formal register is intended or when distinguishing the term from other forms in a specialized context.

Where does catalytical come from?
Catalytical developed as a formal Latinate adjective within the English word family of catalysis, catalyst, and catalytic. Its ultimate source is Greek katalysis, a term associated with kataluein, meaning to dissolve or loosen. The English chemical sense developed from this classical foundation, while catalytical became the less common adjective alongside the now-dominant catalytic.
