⚠️ Voiceless Dental Fricative ⁄θ⁄

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. Blow air gently without vocal chord vibration to produce the unvoiced ⁄θ⁄ sound.

Connected Speech & Natural Conversational Flow

🔗 Consonant-Vowel Linking (Liaison)

When followed by a vowel, insert a subtle glide (/w/ or /j/) to connect into the subsequent word without an abrupt glottal stop.

⏱️ Stress-Timed Rhythm

Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "polyethylene" aligns naturally with adjacent words.
