As an answer to a question of one of you about books to learn languages, I would recommend classics and abridged versions.
Think of universal classics of literature. They provide values too.
Concerning whether it’s ok to use a dictionary while reading my reply is a qualified yes. Dictionaries of English, better if bilingual, are a key factor for understanding a reader or a book. / Photo from: 467x267-dadreadingwithkids-ts www pbs org
