Septimus

Septimus is a masculine given name of Latin origin, derived from the adjective septimus, meaning "seventh." The name historically designated the seventh in a sequence, such as the seventh son or the seventh child in a family, and it reflects the Roman practice of using ordinal elements in naming.

In classical Latin, the root appears in the form septimus; English usage has produced the given-name form Septimus, which has been rare in modern times but appeared in medieval and later texts. The most famous related name is Septimius, as in Septimius Severus, the Roman emperor, though Septimus itself is not the standard Latin form for that ruler. The feminine counterpart is Septima, and various languages have adapted the root in different ways.

In contemporary usage, Septimus is occasionally encountered as a distinctive or literary name rather than a common personal name. It is more likely to be found in historical works, genealogical records, or fiction, where authors may choose it for its classical resonance or to evoke antiquity. The meaning remains tied to the ordinal concept of seventh in a sequence.

Notable bearers are scarce; the form is largely recognized through its Latin roots and its appearance in literature rather than as a common given name today.
