Writers often use “synonymous” to highlight a deep equivalence or subtle nuance between concepts, suggesting that two terms, though seemingly distinct, share an underlying meaning. For instance, it is employed to indicate that certain culturally loaded ideas may be so intertwined that they are treated as interchangeable, whether it be linking age with dignity [1], equating faith with a working hypothesis [2], or even positioning freedom alongside perfection [3]. In other contexts, the term is used critically to argue that two words, despite their apparent similarity, actually conceal important differences in meaning [4, 5]. Moreover, its use extends into the realm of symbolism and allegory, where attributes such as light and truth merge [6, 7] and modern terms like “Orwellian” evoke a shared vision of surveillance and control [8].
