revelation, tell, inform, announce
告 centers on making something known to others: revealing, telling, informing, or announcing. The common thread is the act of conveying information openly.
告 is traditionally explained as combining 牛 (cow) and 口 (mouth), possibly suggesting an announcement or declaration, though the exact historical development is uncertain.
The top ⺧ looks like a simplified cow, and the bottom 口 is a mouth. Imagine a cow opening its mouth to moo loudly, announcing its presence to the whole field.
For コク, picture a rooster crowing at dawn to announce the day: cock-a-doodle-doo -> コク, and the sound tells everyone morning has come.
