The word “diddle” appears to serve a chameleon-like role in literature, assuming multiple meanings and tonal nuances depending on its context. In many of Edgar Allan Poe’s works—most notably in The Raven Edition—the term is deployed in a versatile manner: sometimes as a label for dubious or abstract actions (“He scorns to diddle for the mere sake of the diddle” [1], “A diddler may thus be regarded as a banker in petto” [2], “To diddle is his destiny” [3]), at other times imbuing the narrative with an ironic or playful sentiment (“I reason a priori, and a diddle would be no diddle without a grin” [4], “A very simple diddle, indeed, is this” [5]). In contrast, writers like William Makepeace Thackeray in Vanity Fair have employed “diddle-diddle-darling” as a rhythmic refrain that injects a lighthearted, whimsical quality into dialogue and description ([6], [7], [8], [9], [10], [11], [12], [13]). Additionally, authors such as Jane Austen ([14]), James Joyce ([15], [16]), and even Robert Burns ([17], [18]) have harnessed the term to convey everything from humorous banter to metaphorical movement, thereby underscoring its flexible capacity to mirror both the absurd and the profound throughout literary history.
