In the context of linguistic precision, the concept of affinity refers to a mutual connection shared between individuals or things. It emphasizes that the proper way to describe this relationship is to refer to an affinity with or between entities, rather than suggesting that one entity merely has an affinity for another. This distinction highlights the importance of mutual relationships in understanding affinities.

Moreover, in cases where mutuality is not the focus, the term 'sympathy' is more appropriate. Despite this recommendation, it's important to note that many modern authorities and dictionaries have begun to blur the lines between these terms, not strictly adhering to the original definition. Therefore, while the distinction remains relevant, its usage has evolved over time in everyday language.
