cook

The English word "cook" has a direct lineage from the Latin coquus, meaning "a cook," and the verb coquere, which carried the core sense of applying heat to transform food. This Latin root is itself derived from the Proto-Indo-European base pekw-, meaning "to cook" or "to ripen," a root that also gave rise to words like "concoct" and "biscuit." The semantic journey is remarkably straightforward, moving from the ancient, fundamental domestic and culinary process directly to its modern English equivalent, with the word's form simplifying over centuries from coquus to its current spelling and sound.

The word is a simplex form. It originates from the Latin verb coquere meaning "to cook, to ripen, to digest." It entered English via the Old English cōc (a noun, from Latin coquus) and the related verb cōcian.
