Pamma is likely a pet form of Pamela, a literary name built from Greek elements associated with all sweetness. That literary heritage gives the name a faintly elegant background, even though Pamma itself sounds intimate and informal.
It feels like a name that began as affection and stayed there. As a name, Pamma has a warm, diminutive quality. It is soft and accessible, with the comfort of a nickname and the charm of a rare form.
Because it comes from Pamela, it retains some of that name's old literary polish, but in a much smaller package. Pamma feels affectionate, slight, and pleasantly unpretentious.
