Celda

Rare as a given name but used predominantly in Brazil, the Philippines, and Mexico when it is given, Celda is either a short form of Griselda (or Gricelda), a Germanic name with an Medieval feel, or a feminine spin on Celdon, a Spanish form of the English Sheldon. It coincides with the Spanish word for "cell", as in, a prison cell, or a small, individual room.

Pronounced SEL-duh.
