Chemistry
noun /ˈkemɪstri/ — The invisible current between two people that language can't explain.
Definition
In human interaction: the natural attraction and compatibility between two people; a mysterious quality of connection that exists or doesn't, independent of logic.
Beyond the definition
The word borrowed from science to name what science can't explain — why two people click immediately and others never do, despite all the right conditions. Chemistry is what makes compatibility feel like inevitability.
Origin & history
From Medieval Latin alchimia — alchemy. Applied to human relationships in the 20th century to describe the reactive, almost physical quality of mutual attraction.
