Question 1

What is the difference between Discreet and Discrete?

Accepted Answer

Discreet is about behaviour: tactful, careful, quietly private. Discrete is about structure: separate, distinct, countable. They're pronounced the same and share a Latin root, discretus, 'separate', but they reached English by different routes and now never overlap.
