The word 转告 is formed by combining two individual characters, each contributing a core concept to create a new, unified meaning. The first character, 转 (zhuǎn), carries the idea of "turning", "shifting", or "transferring" something from one state or place to another. The second character, 告 (gào), means "to tell" or "to inform". When placed together, the compound visually and conceptually depicts the action of "transferring a message", that is, taking information you have been told and passing it on to another person, turning the original act of telling into a relayed communication.
