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.

They'd met at a work conference. Nothing special: a training day, a break room, a conversation about coffee machines.
But an hour later, they were still talking, and the coffee machines had been left behind for six subsequent topics, and there was a quality of energy between them — charge, ease, recognition — that neither could account for.
The coffee machines were never discussed. Months later, neither of them could remember how the conversation had started — only that when it ended, they had both felt, for the rest of that week, slightly enlarged.
