In literature, the word "Siamese" is a versatile term that ranges from a precise marker of national and cultural identity to a richly metaphorical device. In historical and travel narratives, it is used factually to denote the people, language, and customs of Siam, as seen in discussions of everyday life and state administration [1, 2, 3, 4]. At the same time, authors employ "Siamese" figuratively to evoke notions of duality or intimate connection—as in references to conjoined or inseparable twins [5, 6, 7]—or to add a whimsical touch in imaginative settings [8]. This broad spectrum of use highlights how the term not only grounds a text in a particular cultural and geopolitical reality but also enriches its literary texture with symbolic meaning.
