The word 接通 is formed by combining two characters, each contributing a core action to create a new, unified concept. The first character, 接, means to "connect" or "receive", picturing the act of linking or picking up. The second, 通, means "open", "through", or "unobstructed", picturing a clear passage. When placed together, the sequence of actions, first making a connection (接) which then results in an open, operational state (通), visually and conceptually forms the idea of "to put through", such as completing a circuit or a phone call, where a link is established and communication flows.
