Etymology
Shirosora (白空) - Shiro (白) means white, a reference to her alter ego as Cure Whitney, and her theme color, which is white. Sora (空) means sky, which would fit the season's theme. Together, her name means "White Sky"

Diamond (ダイヤモンド) - From the English word diamond for the clear colourless precious stone, the birthstone of April. It is derived from Late Latin diamas, from Latin adamas, which is of Greek origin meaning "invincible, untamed".

Cure Whitney - Her Cure alias is based on the given name and surname Whitney, which was originally derived from a place name meaning "white island" in Old English. Like the other Cures, her alias should have be based on the color and/or the jewel. But this didnt work, because of Yukishrio Honoka/Cure White from Futari wa Pretty Cure (Max Heart) and Hishikawa Rikka/Cure Diamond from ''Doki Doki! Pretty Cure''.
