Pronunciation Tips

Non-native speakers sometimes struggle with the pronunciation of "mouth" due to the "th" sound. Here’s how to get it right:

• The "ou" sounds like the "ow" in "cow."
• The "th" is a voiceless dental fricative—place your tongue between your teeth and exhale.

Practice saying:

• Mouth (/maʊθ/)
• Mouths (/maʊðz/) – The plural form changes the "th" sound slightly.

Common Mistakes to Avoid

1. Confusing "mouth" with "mouse" – The pronunciations are different:

   • Mouth (/maʊθ/) vs. Mouse (/maʊs/).

2. Misusing idioms – Saying "foot in the mouth" instead of "put your foot in your mouth" changes the meaning.

3. Overusing slang – Words like "gob" are informal and may not be appropriate in professional settings.
