解説 Definition

覚え方のコツ Memory Tip
男性名では Bob と大文字で書き、Robert の親しみやすい短縮形として覚えます。Robert → Rob → Bob と、昔の英語の愛称で行われた語頭音の交替によってできた形で、William → Will → Bill も同型です。会話で Bob 単独なら人名ですが、小文字の bob には「上下に動く」など別の意味があります。
Remember Bob as the familiar personal-name form of Robert. The historical chain is Robert to Rob to Bob: English nickname formation sometimes replaced the opening consonant to create a rhyming form. A similar pattern appears in William, Will, and Bill. Since it is a name, write Bob with a capital B when referring to a person. Lowercase bob is a separate ordinary word, often a verb meaning to move quickly up and down. Picture calling a friend named Bob to make the name use immediate and natural.

bob の語源・成り立ち Etymology
男性名 Robert の愛称形。Robert はゲルマン語 Hrodebert（hrod＝名声 + berht＝輝く）に由来。Robert → Rob → Bob と英語特有の頭韻交替（R→B）で変化した。同様の例に William → Will → Bill がある。
Bob developed as a familiar rhyming form of Rob, itself a shortened form of Robert. Robert comes from a Germanic name represented by Old High German Hrodebert, combining elements meaning “fame” and “bright” or “shining.” Medieval and early modern English often created nicknames by changing an initial consonant while preserving the rhyme, producing Rob and Bob. The comparable development from Will to Bill illustrates the same naming pattern.
