This, That, and the Buzzy TH German Skips

You may already know that 'think' uses a breathy TH sound made with your tongue between your teeth. But words like 'this,' 'that,' 'mother,' and 'the' use a different, voiced version — the same tongue position, but with your vocal cords buzzing the whole time. German has neither sound natively, so many learners quietly swap in a 'z' or 'd' for this voiced version, turning 'this' into 'ziss' or 'diss.' The fix is simple in concept: keep your tongue tip lightly between your teeth, exactly as you would for 'think,' but turn your voice on before you release it. Try this: put a hand on your throat and say 'this, that, mother, brother' slowly, feeling the buzz start immediately as your tongue touches your teeth. If the buzz cuts in and out, slow down further. This sound shows up constantly in everyday English, so a little focused practice here goes a long way toward smoother, more natural speech.
