Etymology
Origin of subtle
First recorded in 1250–1300; Middle English sotil, from Old French, from Latin subtīlis “subtile” (the b of modern spelling is from Latin ); see subtile
Explanation
Something that is subtle is not obvious: a professional food taster might be able to perceive subtle differences of flavor that most people don't notice. Subtle is used for things that are hard to describe because of their complexity or delicacy: a way of thinking, arguing, or creating a work of art. The word is pronounced like "suttle" and it was originally spelled that way when it was borrowed from Old French, but the b got imported to make the word look more like its ultimate source, the Latin adjective subtilis. But don't pronounce the b — that won't be very subtle!
