The word 住址 is formed by combining two characters, each contributing a core idea to create a new, specific meaning. The first character, 住 (zhù), carries the fundamental concept of "to live" or "dwelling". The second character, 址 (zhǐ), provides the notion of "location", "site", or "foundation". When joined, the combination logically progresses from the general action or state of residing (住) to the precise physical point or place (址) where that occurs, thereby naturally arriving at the complete concept of "address" or "place of residence".
