What is the meaning of the name Sannu ?

The baby name Sannu is a Unisex name , 2 syllables long and is pronounced SAN-noo (approx. /ˈsæn.nu/),SAHN-noo (approx. /ˈsɑn.nu/).

Sannu is Hausa, Scandinavian in Origin.

Sannu is a multicultural given name with several roots. In South Asia, it aligns with Sanu, from Sanskrit sānu “mountain ridge, summit,” and with Nepali sanu “little/younger,” used affectionately for a youngest child. In Hindi–Bengali naming it emerged in the late 20th century as a cozy pet name promoted to official status, especially for boys but now unisex.

In Finland and Estonia, Sannu functions as a diminutive of Susanna (from Hebrew Shoshannah “lily”), alongside Sanni and Sussu; use peaked with the late‑20th‑century trend of formalizing nicknames. In Hausa‑speaking West Africa, Sannu echoes the everyday greeting sannu (“well done,” “sorry,” “hello”) and is occasionally chosen to convey kindness and empathy. Variants and related forms include Sanu, Sanni, Sanna, and Susanna; in South Asia, Sanju appears as a cognate-style nickname. Meanings therefore range from “little one” or “youngest,” to “mountain ridge,” to “lily,” with a modern aura of warmth.
