Common Pronunciation Traps & Learner Mistakes

⚠️ Voiced Dental Fricative ⁄ð⁄

The Trap: Many learners substitute "th" with "s", "z", "t", or "d".

How Native Speakers Say It: Place the flat blade of your tongue lightly between your upper and lower incisors. Vibrate your vocal cords while pushing air through to produce ⁄ð⁄.

⚠️ Intervocalic Tap / Flap [ɾ] in American English

The Trap: Pronouncing a hard, aspirated [tʰ] in casual conversation can sound overly formal in North America.

How Native Speakers Say It: In American English, a single "t" between vowels quickly taps against the alveolar ridge like a soft "d" ([ɾ]). In British English, maintain a crisp aspirated [tʰ].
