The character in the “ص ض ط ظ ق — the heavy consonants and the deep q” group

The emphatic consonants are "heavy" sounds with no soft partner: the tongue is pulled back and the whole syllable darkens. The pairs circle round: heavy s/d/t/z, told apart by skeleton and dots. Next to them the deep q, made down in the throat — it shares its sound with ف but not its depth.

How to remember this character

A single letter is the hardest thing to remember: memory has nothing to hold on to — a character has no meaning. A three-step loop works: see the character, try to recall the sound (for «daad» it is “d (emphatic)”, as in the word “ضيف”), see the right answer.

And come back to it the next day, not in an hour: a check a day or two later beats a check the same day. Nobody holds the whole alphabet — 28 letters — at once.

It is better to test yourself the next day than at the end of the same session. That is why a word comes back to you tomorrow.checked many times
