Etymology: "Knowledgeable" is a straightforward formation: the noun "knowledge" with the suffix "-able" attached, giving the sense of being capable of being known or, more commonly today, of possessing knowledge. The suffix traces back through Latin "-abilis" and "-ābilis", passing into Old French as "-able" and then into Middle English, where it became a productive ending for forming adjectives from verbs and nouns. The base noun "knowledge" itself is English, built from the Middle English "knowleche" with the older verb "knowen", and its deeper roots lie in the Proto-Indo-European word for knowing that also gave English the "-ledge" element. The compound is therefore a native English stem with an inherited Latinate suffix, a mixture that is common in English adjectives. Because the word is a plain combination of a familiar noun and a suffix, its meaning has stayed close to its parts: someone who is knowledgeable is well informed, with the suffix supplying a sense of capability or possession rather than any dramatic shift.
