One way to hold it: the distance from the surface down to the bottom grows. Whatever the thing is, it gains more 'down' than it had before.
From the word’s history
Simply deep + -en, the suffix that turns an adjective into 'become/make more so' (as in widen, darken, soften). So the word is literally 'become deep', and every extended sense is the vertical picture of deep applied to something that has no real bottom.
構詞很單純:deep(深)+ -en(使…變得、變成),跟 widen(變寬)、darken(變暗)、soften(變軟)同一個模子。所以 deepen 字面就是「變深」。有意思的是引申都不是來自 deepen 本身,而是繼承 deep 的比喻:英文早就用「深」去講感情、理解、顏色和聲音,deepen 只是把那些「深」再往下推一格。
