Across a broad literary spectrum, the word "purchase" functions both in its literal monetary sense and as a metaphor for the acquisition of intangible values. In some works, it clearly denotes a formal transaction—whether buying furniture through instalments [1], investing in land [2], or conducting everyday bargains like purchasing tea [3] or a costly ornament [4]. In other contexts, it serves a figurative purpose, reflecting the human desire to attain freedom or honor, as when liberty is too dear to be bartered [5], or when sacrifice is deemed no substitute for freedom itself [6]. Moreover, its use in varied settings—from royal decrees [7] and economic treatises [8] to dramatic dialogues in romance and adventure [9]—illustrates how "purchase" consistently conveys both the tangible and symbolic dimensions of exchange.
