Grammar
Arabic is more regular than it looks, but its regularities are not the ones English-speaking learners expect.
Arabic grammar has a reputation for difficulty that is partly earned and partly a misunderstanding. Yes, there are three grammatical cases, two genders, three numbers (singular, dual, plural), ten common verb forms, and a system of broken plurals that has to be memorized by hand. But the language is also built on a single elegant idea — the consonantal root — that, once internalized, makes vocabulary expand in front of you. From the root ك ت ب (k-t-b), the language generates kataba "he wrote", kitaab "book", maktab "office, desk", maktaba "library, bookshop", kaatib "writer", maktoob "written, letter". Learn the patterns and you learn families of words at a time.
The order of the pages in this section is deliberate. Begin with roots and patterns — without it, the rest of the grammar feels arbitrary, and with it, much of the rest is recognition rather than memorization. From there, work through the noun system: nouns, definiteness and the article الـ, gender, plural, and cases, then adjectives and pronouns. The verb pages — verbs overview, the ten forms, tense and aspect — are the centre of the system and worth slow, repeated reading. Sentence structure, negation, and questions tie the pieces together. The إضافة construction deserves its own page because it is the way Arabic does what English does with "of" — and it shows up everywhere. How numbers behave is its own quiet horror, with three- and four-letter numbers triggering case and gender rules that even native speakers sometimes flub.
One caveat. The grammar described here is mostly that of Modern Standard Arabic. Spoken dialects simplify in predictable ways: most drop the case endings entirely, collapse the dual where they can, and use a single negation particle in place of the formal pair. We point those simplifications out as we go, and the Dialects section covers them in detail.
