seculum

Seclum, or seculum, is a Latin noun (neuter) that denotes a long span of time, an age, era, or generation. In classical and medieval Latin, the term refers to a broad period rather than a precise count of years, and its exact length varies with context. The standard and more common form in most Latin dictionaries is saeculum, with seculum appearing as a manuscript or regional variant in some texts.

Etymology and forms: The widely used form is saeculum, derived from the Latin root meaning age or lifetime. Seculum appears in certain manuscripts and later recensions as an alternative spelling, but saeculum is generally preferred in modern scholarly usage. Both spellings convey the same general notion of a substantial historical or generational span.

Usage in Latin literature and theology: In classical authors, saeculum often denotes a long period such as a generation or a century, depending on the writer and context. In ecclesiastical and medieval Latin, the phrase in saecula saeculorum—literally “in the ages of ages”—appears in liturgical contexts and has been translated as “forever” or “for ever and ever.” This formula underscores the conceptual span of an age rather than a fixed chronological unit.

Modern usage and significance: Today, the term is primarily of interest in the study of Latin language, classical history, and Christian liturgy. When encountered in texts, seculum typically signals a broad, indefinite era rather than a precise date. The word contributes to discussions of historical time frames, generations, and the way ancient authors frame long periods.
