Definition: The word "appropinquation" in Greek is used to describe an emotional or mental state where one feels the emotions of another. Specifically, it's a term from Jewish religious tradition that refers to a person's attachment to someone else through their actions and behavior. This can manifest as feelings of love, affection, or desire for them, but not necessarily sexual attraction. It's often used in a metaphorical sense to describe the relationship between two people who are deeply connected emotionally.
