According to the un-aired pilot episode, Katara’s name was originally 'Kya', which was later used for her deceased mother instead. In “Tales of Ba Sing Se”, Katara’s name was written as卡 塔 拉. Kǎ (卡) means to check, block, or card; Tǎ (塔) means pagoda; and Lā (拉) means to pull. The character 'Lā' appears in the first season's finale, while the character 'Kǎ' also appears in Sokka's name.
