is not limited to simply "acting cute", and includes several changes to speech, such as
affrication,
stopping, and /j/ insertion. Instead of a binary distinction between "formal" and "informal" language, speakers strategically position themselves in relation to their interlocutors. As a result, aegyo attains social significance by modifying established patterns of polite and intimate speech, rather than functioning as a separate register. Playful modifications of sentence-final forms, such as variants of the polite ending -yo, allow speakers to express softness, affection, and emotional nuance while maintaining attentiveness to the listener and the relationship Due to the strong association between Korean speech levels, hierarchy, and age, the use of aegyo underscores who is authorized to employ a cute speech style, toward whom, and in which contexts. identifies aegyo as a specialized register for expressing affection and cuteness, particularly in interactions with intimate interlocutors, and documents its occurrence in both spoken Korean and written communication on Twitter. This evidence demonstrates that the social meaning of sentence endings is variable. Although a polite ending may signal deference, stylized aegyo can also convey warmth, closeness, or playful dependence. Therefore, Korean speech style can simultaneously index respect and intimacy, rather than conveying a singular social meaning. Crosby also argues that aegyo represents a socially recognizable style that encompasses both linguistic and non-linguistic features. In a study of couples in the Seoul area, participants most frequently associated aegyo with nasality and a distinctive rising-falling intonation pattern, with younger speakers more likely to connect phonetic and phonological variants to aegyo. Crosby further suggests that aegyo and its nasal qualities function as forms of positive politeness, signaling whining, caring, and affectionate stances. This perspective is important for understanding Korean speech levels, as it shows that social hierarchy is negotiated not only through honorific grammar or strict formality. Speakers also foster closeness by integrating affective cues into polite or semi-polite forms, especially in romantic or intimate relationships Speech-level variation in aegyo has become increasingly visible among younger generations through digital communication. Jang's corpus analysis of Twitter data shows that aegyo is actively represented in text, with users altering spellings and endings to convey cuteness in writing as well as in speech . Crosby's dissertation similarly includes aegyo-like text messages in participant readings, demonstrating that these forms circulate across both spoken and written interactions rather than being limited to face-to-face conversation . As a result, social media allows younger speakers to adapt speech-level markers from offline contexts as stylized indicators of intimacy, humor, or personal identity. == Relation to gender roles and sexism ==
