01Further back than any English k
ق (qāf) is a stop, like k: the tongue closes the airway completely, then lets go. The difference is the place. ك (kāf) is made where English makes k, with the back of the tongue against the soft palate. ق is made further back still, with the very back of the tongue against the uvula, the small lobe that hangs at the back of the mouth. Transliteration writes it q.
The q has nothing to do with the qu of English “queen”: no w follows it. And it is not a k said harder. It is a different consonant, and Arabic uses the two to tell words apart. This lesson is about formal Arabic and assumes you can read the letters and short vowels.
Starts with ق: the closure is deep at the back, and the a after it sounds a little darker.
Starts with ك: an ordinary k, and a bright a.
02How to find ق
Say “key”, then “cool”. Your tongue already touches further back for the k of “cool”. Keep sliding the contact point backwards, past where any English k goes, until the very back of your tongue meets the back of the roof of your mouth. Close there, hold for an instant, then release into the vowel: قَـ.
Another way in: start a gentle gargle and notice where it rattles. ق is made in that region, but with a full closure instead of a rattle, and with the voice off: ق is whispered like k, not buzzed like g.
Check three things. The air stops completely before the release: if it keeps rubbing through and sounds gargled, you have made غ. The voice is off during the closure: a hand on your throat feels no buzz until the vowel starts; a buzz means you have made a deep g, not ق. And the vowel after it is a shade darker: if it sounds like the a of “cat”, your tongue has slid forward and you have made ك.
With ق. Close deep, then open into a long, dark ā.
With ك. The same word shape, with a forward k and a brighter ā.
03Listen to the vowel
ق belongs to the letters Arabic grammarians call heavy: they pull the back of the tongue up and darken the vowels next to them. The effect is milder than after ص or ط, but it is there: after ق, a leans towards the a of “father”; after ك it stays closer to the a of “cat”.
There is a second cue you can feel. ك comes with a small puff of air, like English k; ق is released without one. Hold a hand in front of your mouth and compare. If you cannot yet hear the consonants apart, listen to the vowel after them and feel for the puff.
With ق: a darker, deeper ā.
With ك: a brighter ā.
04ق is not غ
غ (ghayn) is made in the same region as ق, against the back of the soft palate or the uvula depending on the speaker. The difference is how: ق closes completely and releases with the voice off, while غ never closes and lets voiced air rub through, a soft gargle close to the r of Parisian French.
So the test is whether the air stops. For ق there is a moment of complete silence before the release. For غ the sound runs on.
With ق: a closure and a clean release.
With غ: no closure, a soft continuous gargle.
05In the middle and at the end of a word
Away from the start of a word, ق is easy to flatten into a k. Keep the closure deep wherever it falls. At the end of a word, finish on the release instead of swallowing it.
In several spoken varieties, ق is said as a hamza or as a g. In formal Arabic it is always q, and that is the sound to learn here.
ق closes the first syllable: waq-tun. Keep it deep, not a forward k.
Ends in ق, shown as you say it in pause (the full form is شَوْقٌ).
Ends in ك, also in pause (the full form is شَوْكٌ). Only the last consonant separates longing from thorns.
