The word says what it is: bee + wax, the wax a bee makes. Hold that picture — a warm yellow block that smells of honey, melted down into candles, rubbed into an old table, pressed into a lip balm. Everything in the first meaning is that block. The second meaning is a different kind of thing entirely: the word has been borrowed as a joke, because it sounds like business.
這個字自己就把答案講完了：bee（蜜蜂）＋ wax（蠟），也就是蜜蜂做的蠟。可以想成一塊溫溫的黃色蠟，帶著一點蜂蜜味——融掉做成蠟燭、抹進舊桌面、壓成一條護唇膏。第一個意思裡的每一種用法，都還是那一塊蠟。第二個意思就不是同一回事了：那是有人拿這個字開玩笑，因為它聽起來很像 business。
From the word’s history
The source entry gives bee + -s- + wax.
來源資料把它拆成 bee ＋ -s- ＋ wax。這種透明的複合詞不需要背，看得懂兩個部分就看得懂整個字：誰做的、是什麼材料。
