Is Arabic hard or easy, simple or complicated? You sometimes hear the argument that Arabic is easy because there are only two verb tenses and the verbs are formed according to patterns, from a three-letter root.
From what I’ve been told, native speakers of Arabic don’t learn the measures the way we do; some western linguist or grammarian or whatever invented it for our sake. Anyhow, my point is, if you’re trying to learn Arabic, it couldn’t hurt to read Keith Massey’s book, Intermediate Arabic for Dummies.
As an Arabic student acquaintance of mine said, “If Dr Massey wrote another book, I’d read it.”
