Synonym discussion
Sense: adjective/1
All five words describe someone with a good amount of knowledge, but they differ in how that knowledge was acquired and what type it is. 'Well-read' and 'widely read' are nearly interchangeable — both emphasise that the knowledge came from reading books. 'Knowledgeable' is the broadest term: you can be knowledgeable about cars from hands-on repair work, with no reading at all. 'Learned' is more formal and suggests deep, academic study, often including university-level education. 'Well-informed' focuses on awareness of current events, facts, and recent developments rather than deep book knowledge. A well-read historian may also be well-informed about today's politics, but being well-informed does not require having read many books.

Etymology
A compound formed in English from the adverb 'well' (Old English 'wel', meaning 'in a good manner') and the past participle 'read' (Old English 'rædan', meaning 'to advise, interpret, or read'). The combination has been used since the early 16th century to describe someone who has read widely and gained knowledge as a result.
