One way to hold this word: everything starts from one short, high sound a machine makes. From there English lets the sound spread in three directions. It becomes the action — the machine bleeps. It becomes the box that makes it, the little device a doctor carries. And because that sound is what television puts over swearing, it becomes the cover for a rude word, and then the stand-in for the word itself. Even the music named bleep is just that sound, played on purpose for an hour.
From the word’s history
Wiktionary gives the origin as simply onomatopoeic: the word copies the sound. That is why the core image and the word are the same thing — saying bleep is making a small version of the noise.
Wiktionary 對這個字的說明只有一個詞：擬聲（onomatopoeic），也就是用發音模仿那個聲音。所以這裡的核心畫面跟字本身其實是同一件事——唸出 bleep，就等於把那一聲小小地重演一次。
