The only thing confirmed about this group so far is that 'Produce 101's Jeon So Yeon is included in the lineup.
It seems that the girl group can also be referred to as 'G-I-DLE', or fully 'GIRL-I-DLE', as a play on their Korean name, which can literally translate to "(Female) Children". (Remember, the Korean word 아이들 [pronounced 'ah-ee-deul'] means "children".)
The logo itself contains a lowercase 'i' in the beginning, followed by the last character of the group's Korean name flipped sideways.
Stay tuned for more info on I-DLE's debut coming soon!
