What Caia means

Caia is a given name.

The naming story behind Caia

Charlotte M. Yonge’s 1884 History of Christian Names includes the exact spelling Caia in its glossary. The entry labels it feminine and points to printed page(s) 131.

The glossary’s abbreviated description reads: “Lat. rejoiced in”. This is the historical author’s wording, including its language abbreviations and any proposed interpretation. It is presented as historical evidence, not as a verified modern translation. Victorian classifications and root explanations can differ from later linguistic research.

For Caia, the current short meaning therefore remains unconfirmed. Establishing its modern etymology requires a current reference that documents the exact form and its relationship to the proposed earlier words.

Shading is the share of that state's recorded girls given this name, not the raw count — otherwise the map would just show which states are biggest. Unshaded states have no published records for this period. U.S. birth records suppress state-year counts below 5; state counts therefore don't add up to the national total. Every state links to its full rankings.
