knowledgeable

> knowledgeable
knowledgeable is frequently misspelt. Note the d, which is often omitted in error, the e after the g, which is also liable to be omitted in error, and the -able ending. Knowledgeable means "knowing a lot, well-informed", as in "take advice from people more knowledgeable than himself" and "He is extremely knowledgeable on the subject of ancient Greece".
