Getting Closer to the Meaning of Propinquity

Propinquity and its cousin "proximity" are related through the Latin root prope, which means "near." That root gave rise to "proximus" (the parent of "proximity") and "propinquus" (an ancestor of "propinquity"). "Proximus" is the superlative of "prope" and thus means "nearest," whereas "propinquus" simply means "near" or "akin," but in English "propinquity" conveys a stronger sense of closeness than "proximity." (The latter usually suggests a sense of being in the vicinity of something.) The distinctions between the two words are subtle, however, and they are often used interchangeably. "Propinquity" is believed to be the older of the two words, first appearing in English in the 14th century; "proximity" followed a century later.
