caffeine-free

The compound adjective 'caffeine-free' is a modern formation that follows a common English pattern for describing the absence of a substance. The first element, 'caffeine', entered English in the 19th century, tracing its lineage through European languages back to the Arabic qahwah for coffee, with the suffix -ine marking it as an alkaloid compound. The second element, 'free', is an ancient Germanic word whose core meaning of "not in bondage" evolved to broadly signify "exempt from" or "without." When combined, the literal "free from caffeine" directly and logically conveys the modern product label meaning of containing no stimulating caffeine, showcasing how English readily creates transparent descriptive terms from existing lexical components.

Structure: caffeine (substance) + free (without) - caffeine: A borrowing from French, ultimately from German Kaffein, from Kaffee (coffee) + the chemical suffix -ine. The root is from Ottoman Turkish kahve (coffee). - free: From Old English frēo (free, exempt from, not in bondage), from Proto-Germanic frijaz (beloved, not in bondage), from Proto-Indo-European priHós (dear, beloved).
