One way to picture it: water keeps coming into a container that is already full, so it climbs to the rim and spills over the edge — the container cannot hold any more, and the extra has to go somewhere.
From the word’s history
From Old English oferflōwan — ofer "over" + flōwan "to flow": literally to flow over the edge.
來自古英語 oferflōwan,就是 ofer(越過)+ flōwan(流)。這個字幾乎是把畫面直接寫在字面上——「流過去、流出邊界」,所以它的每個引申用法都還看得見那道被越過的邊。
