Cheek by jowl means very close together, often in a crowded, cramped, or uncomfortably intimate way. In poetry, it can describe bodies in a city street, graves in a churchyard, houses in a poor district, strangers in a train, or ideas forced into proximity. The idiom is useful because closeness may imply warmth and fellowship, but also tension, contagion, surveillance, or social pressure. Its physical vividness makes abstract relations spatial: people, classes, memories, or eras may exist uneasily side by side.

Cheek by jowl means very close together, often in crowded or intimate proximity. Its bodily language gives closeness a tactile quality: faces, jaws, and cheeks nearly touch. In poetry it can describe city life, cramped houses, social mingling, or the unsettling nearness of opposites such as wealth and poverty. The phrase is slightly old-fashioned, which can add texture or historical flavour.
