Definition & pronunciation of glass

Okay, let's break down how to pronounce "glass" in English. It's a tricky one because it's often mispronounced!

Here's the breakdown:

  • The General Rule: Most people incorrectly pronounce it as "glahs." However, the correct pronunciation is "glæs".

  • The 'gl' Sound: The key is the "gl" sound. It's a voiced palatal fricative. This means:

    • Voiced: You need to vibrate your vocal cords – you should feel a little buzz in your throat.
    • Palatal: The sound is produced with the middle of your tongue raised towards the hard palate (the roof of your mouth, just behind your front teeth). It’s a very subtle raise.

  • The 's' Sound: The 's' sound is a standard 's' sound – like in "sun."

Putting it together: "glæs"

Imagine you're making a very quick, gentle sound like you're almost clearing your throat, but with your tongue lightly raised towards the roof of your mouth. It's a fast, subtle "gl" followed by a clear "s."

Here are some ways to hear it:

  • Google: Search for "how to pronounce glass" on Google and listen to the audio examples.
  • Forvo: https://forvo.com/word/glass/ - Forvo is a website where native speakers pronounce words.
  • YouTube: Search on YouTube for “how to pronounce glass” – you’ll find many videos demonstrating the pronunciation.

Tips for practicing:

  1. Start with "gluh" (like the German word). Then, quickly and lightly raise your tongue towards the roof of your mouth as you say "s."
  2. Listen closely to native speakers. Pay attention to the placement of their tongue and the vibration of their vocal cords.
