The word “lieu” has been employed in literature with a dual focus on both its literal sense—denoting a place or location—and its figurative use to indicate substitution or an alternative. In many English texts, the phrase “in lieu of” is repeatedly used to mean “instead of,” as seen in contractual or formal contexts ([1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21]). Meanwhile, French sources and translations provide definitions that highlight “lieu” as a physical space—ranging from a display area ([22]), a hearth or home ([23]), a battlefield ([24]), to even more abstract or specialized locations like a theater ([25]) or camp ([26]). The term also appears in creative literary exchanges and allegorical statements—for instance, illustrating alternative choices or substitutions in settings as diverse as military distinctions ([27]), financial settlements ([28], [29]), and symbolic exchanges ([30], [31], [32]). Overall, “lieu” demonstrates a rich versatility in literature, expanding from its literal geographical origins to metaphoric and formal substitutions across various genres and eras.
