The 28 letters, one page each
A reference being written letter by letter — sound, forms, confusions, examples, handwriting.
This section is being built letter by letter. Each page covers a single letter in detail: how it sounds (with English approximations and a note on what English speakers tend to get wrong), the four positional forms — isolated, initial, medial, final — drawn at large size, the letters it can be confused with on the page, a handful of example words you actually meet in real text, and a short note on how the letter is typically shaped by hand as opposed to in print. Where a letter has multiple realisations across dialects (the famous case is ج jiim, which is a hard g in Egypt and a j in most of the rest of the Arab world), we try to flag that without pretending one is more correct than another.
The pages are best used as a reference, not a course. If you are starting from zero, work first through the alphabet at a glance, which gives you all twenty-eight in one view, and then through how letters connect, which explains the system that makes the four positional forms make sense. After that, dip into the individual letter pages whenever a particular letter is giving you trouble — the emphatics (ص, ض, ط, ظ) and the throat consonants (ح, خ, ع, غ, ق) are the usual culprits.
The list below is in the traditional alphabetical order. Pages are linked as they go live; broken links here mean that page is still being written. We would rather leave a gap than ship a page we have not had a native speaker review.
