Honorifics in child-directed speech

Abstract How are honorifics, which are socially meaningful and socially conditioned, acquired, when their appearance in child-directed speech cannot replicate their use in adult-directed speech? In this paper, we conduct corpus and experimental studies aimed at characterizing the use of honorifics in child-directed speech in Korean. We find that the addressee honorific - yo is present at notable rates in child-directed speech, although the use of - yo in child-directed utterances is rated less natural than its absence. We further find that while - yo is given lower ratings for the presence of relevant social meanings when in child-directed speech compared to adult-directed speech, the use of - yo in child-directed speech is still significantly associated with these meanings. This suggests that while the presence of honorifics in child-directed speech is somewhat unexpected, such uses of honorifics nonetheless carry relevant information about the social meaning of honorifics.
