The word "squalid" has been deftly employed in literature to evoke both a palpable sense of physical decay and a nuanced moral degradation. Authors often use it to describe environments steeped in poverty and neglect, as seen in depictions of dilapidated tenements and grim urban quarters ([1], [2], [3]), where the very setting becomes an emblem of despair. Simultaneously, the term conveys the degradation of character and vice, painting portraits of individuals or social practices steeped in moral filth—from the portrayal of "hapless squalid Marat" and the vice-ridden corridors of human existence ([4], [5], [6]) to the metaphorical representation of a life marred by squalid compromises ([7], [8]). In this way, "squalid" functions as a versatile literary device, enriching the narrative by linking the external environment with the inner desolation of its characters.
