Sharenna appears to be a variant of Sharon, the Hebrew place name meaning a fertile plain. That gives the name a gentle landscape root and a biblical backdrop, both of which contribute to its soft, grounded character.
The added ending makes it feel more ornate and modern than the base form. Sharenna has a familiar, flowing rhythm that makes it easy to wear while still feeling slightly uncommon. It sounds feminine and polished, with the kind of embellished structure often favored in modern naming. The result is a name that feels rooted, graceful, and lightly decorative.
