Etymologikos

Etymologikos is the transliteration of the Greek adjective ετυμολογικός, meaning "etymological" or "pertaining to etymology." In Greek, the suffix -ικός (-ikos) forms adjectives that indicate relation to a field or quality, so etymologikos describes things related to the study of word origins. The related noun is ετυμολογία (etymology).

In linguistic usage, etymologikos describes materials, analyses, or questions dealing with the origin of words, their historical forms, and the changes in form and meaning over time. In Greek-language dictionaries and grammars, sections that trace a word’s history are often labeled with etymologikos or include etymological notes; similarly, modern bilingual dictionaries may present an ετυμολογία line to indicate its origin.

The term corresponds closely to the English word etymological and to the broader field of etymology, which is a branch of historical linguistics concerned with the origin of words, their original forms, cognates across languages, and semantic changes. The English word etymology derives from Latin etymologia, itself from Greek etumología, formed from elements meaning “true” (etymon) and “study” (logos).

As a linguistic descriptor, etymologikos does not denote a separate discipline but serves as a label within Greek-language texts to signal etymology-related content. In multilingual or transliterated contexts, it may appear to indicate etymological information in dictionaries, glossaries, or academic works.
