Keltum
Keltum is the Maghrebi/Amazigh vocalization of the classical Arabic name Kulthūm; its origin is Arabic but the form Keltum is regionally North African.
The root name Kulthūm is historically attested among early Muslim women (several historical figures bore the name); Keltum is the North African variant preserved in later registers.
Linguistically it derives from Arabic كُلثوم (Kulthūm), traditionally glossed as 'full‑faced' or 'round‑cheeked'.
Keltum is rare outside the Maghreb; it remains uncommon and is mostly found in Morocco, Algeria, and among Amazigh communities.
No established male form exists; the name is specifically a feminine given name in Arabic usage.
