Etymology: Ancient Greek speakers built "alētheia," meaning "truth," literally "unforgettableness" or "non-concealment," from "a-" (not) and a root tied to forgetting and hiding, and then attached "-logia," the suffix for systematic study, to it. The result is a word that announces its own job: a study of truth. The compound is a modern coinage, not a term from antiquity. Its parts are classical, but the combination was assembled much later, in the scholarly vocabulary of the modern period, so no ancient writer used it. The pattern is the same as in other "-logy" fields such as biology or theology, where an existing root is joined to "-logia" to name a discipline. The word is used in a narrow, specialized sense: the examination of competing claims and principles about what truth is and how it can be established or measured. Its strength lies in naming that inquiry directly, separating it from neighboring fields that deal with knowledge or belief.
