From Sino-Korean
慶 (gyeong) meaning "congratulate, celebrate" or
敬 (gyeong) meaning "respect, honour" combined with
子 (ja) meaning "child". This name can be formed of other hanja character combinations as well. Korean feminine names ending with the character
子 (a fashionable name suffix in Japan, read as
-ko in Japanese) became less popular after Japanese rule of Korea ended in 1945.
