Struggling to differentiate the 'th' and 'dh' sounds in Arabic loanwords

Focus on the 'blade' of your tongue, not just the tip. For 'dhahabu' (gold) and 'thelathini' (thirty), you want your tongue slightly flattened against the back of your upper front teeth rather than poking through them like an English 'th'. A great drill: whisper the word 'the' and hold the friction at the start. Don't let your tongue touch the roof of the mouth. In Tanzania, you'll hear these pronounced very clearly in formal speech, but many people in informal contexts will actually drift slightly toward a 'z' or 'd' sound. Don't sweat perfection—clarity in your vowel length will often mask minor consonant slips.

I struggled with this for months. My breakthrough was realizing that in Swahili, these loanwords are often treated with a slightly more 'sharp' percussive quality than in English. Try the 'pencil drill': hold a pencil horizontally between your teeth while practicing the words. It forces your tongue to interact with the teeth correctly. Also, listen to Tanzanian news broadcasts (TBC Taifa) rather than Kenyan pop music, as the loanword pronunciation in the news is much more deliberate and standard. If you're defaulting to English 'th', you're likely putting too much air through. These sounds should be 'tighter' and use less breath.

You’re likely hitting the English 'th' because you’re anticipating the vowel too early. Try breaking the word: 'dh-ah-ha-bu'. Sustain that fricative for a full second before transitioning to the vowel. If you can sustain the sound without it turning into a 'z' or an English 'th' breath-puff, you’ve got the placement. Record yourself doing this intentionally exaggerated version, then shorten the duration of the fricative by 10% each day. It’s a common trap to treat these as English sounds; treat them as a 'd' or 't' that you simply refuse to close the airway for completely.
