This study aims to investigate the use of emojis in an Indonesian Intergenerational family WhatsApp group to reveal the types and functions of emojis used in the setting where members from various gender and age groups communicate online. The participants were 26 male and 16 female WhatsApp users aged 21 to 66 years old in the group. The data were collected from five months of interaction in the WhatsApp group. The findings showed that both men and women from various age groups used the following emojis, namely 'folded hands', 'beaming face with smiling eyes', 'palms up together', 'thumbs up', and 'face with hand over mouth', in the WhatsApp group communication. In terms of function, both men and women use emojis for 1) attitude/emotion enhancer, 2) attitude/emotion signal, 3) backchanneling, 4) humour, and 5) illocutionary force. The findings contribute to research on the use of emojis relatively scarce in Indonesian contexts. The findings also suggest how to communicate using emojis in forums with members from various ages and genders.
