In the Korean language, ‘geurium(yearning; attachment; longing)’ is intrinsically connected to feelings of love and the experience of loss, relating closely to core Korean emotional expressions such as ‘jeong(bond; feeling. love; affection)’ and ‘han(resentment; deep sorrow)’. Although there have been numerous studies aimed at defining the attributes and semantic categories of emotional lexicon, they have often resulted in divergent opinions. This paper focuses on the complexity of ‘geurium’ and how its meaning changes depending on the situational context. It examines ‘geurium’ and associated verbs that derive from ‘geuripda(to miss or to long for)’, such as ‘geurium’, ‘geuriwohada(to feel longing)’, and ‘geuriwojida(to become missed)’, to identify the semantic properties of ‘geurium’ as expressed in Korean. ‘geurium’, as identified through co-occurring lexicon, is an emotion that positively regards an absent entity and is characterized as a potential and continuous feeling. It is also associated with ‘sad actions and emotions’ and manifests ‘suddenly’, moving ‘from outside in and from inside out’. By analyzing Korean popular songs that reflect these semantic properties, this study proposes potential educational approaches to understanding the sentiment of ‘geurium’.
