The word “strait” has been rendered in literature both as a descriptor of narrow, often treacherous geographical passages and as a metaphor for constricted or difficult circumstances. In the maritime realm, authors such as Jules Verne vividly evoke physical straits—from the treacherous Torres Strait ([1], [2], [3]) and the Strait of Gibraltar ([4], [5]) to the fabled Strait of Magellan ([6], [7]), painting passages that are crucial in navigational and exploratory narratives. At the same time, “strait” is employed in a figurative sense to denote states of confinement or distress, as seen when characters complain of being in a “strait-waistcoat” ([8], [9], [10]) or find themselves “in a great strait,” symbolizing desperate predicaments ([11], [12], [13]). Even in classical works, the term is used to evoke symbolic thresholds, such as the “strait gate” in allegorical journeys ([14], [15]), indicating the narrow passage to a higher or redeemed state. Thus, across diverse genres and periods—from historical and geographical treatises ([16], [17], [18]) to poetic and narrative explorations ([19], [20], [21])—the word “strait” serves as a rich, multifaceted metaphor that conveys both literal and figurative restrictions in human experience.
