This study examines the latest trends and changes in Korean naming practice within the socio-onomastic framework. Using the data from the website of the Supreme Court of Korea, the present research analyzes the linguistic features of baby names registered between 2010 and 2021 and identifies how these features reflect the social and cultural characteristics of Korea. The study focuses on popular names (and their first and last letters), syllable structure, types of the coda consonant, and unisex names. The most preferred names for males and females were ‘서준 (Seo-Jun)’ and ‘서윤 (Seo-Yun)’, respectively. Both male and female names showed a preference for ‘지(Ji)’ as the first letter of the name. ‘준 (Jun)’ and ‘은 (Eun)’ were the most frequently used second letter for male names and female names, respectively. For both male and female names, the syllable structure without a coda is increasing while the CVC structure is rapidly decreasing. For both genders, ‘ㄴ’ is the coda consonant with the highest frequency. Male names were found to end with a coda such as ‘ㄱ, ㄴ, ㄹ, ㅁ, ㅂ, ㅇ, ㅊ’, but the use of obstruents ‘ㄱ’, ‘ㅂ’ is sharply decreasing. For female names, ‘ㄴ, ㄹ, ㅁ, ㅇ’ were almost categorically used for the final coda. The study also finds that ‘unisex names’ have significantly increased since the 1970s in Korea.
