The word "mongrel" in literature serves as both a factual descriptor of mixed-breed entities and a metaphorical tool to signal moral or cultural ambiguity. In scientific texts, as seen in Darwin’s discussions, it carries a neutral technical meaning to denote hybrids resulting from reciprocal crosses, whether in plants or animals ([1],[2],[3],[4]). In contrast, literary authors often employ it to evoke disapproval or to highlight a perceived lack of purity—comparing characters or traits to inferior, mixed-breed animals, as reflected in works by Dickens and Maugham ([5],[6]). Additionally, its usage is extended to language and cultural identity, subtly critiquing the complexity of blended heritage or dialects ([7]). This dual function enriches the text, imbuing physical descriptions with broader connotations about identity and worth.
