Definition & pronunciation of substitute

Okay, let's break down how to pronounce "substitute." It can be a tricky one for some! Here's a breakdown:

1. Syllables:

The word is divided into three syllables: sub - stit - ute

2. Pronunciation Breakdown:

  • Sub: Sounds like "sub" as in "subway." Short 'u' sound.
  • Stit: This is the trickiest part. It's pronounced like "stit" as in "stitched." It’s a short "i" sound and a short "t" sound. Don't try to say "st-it" – it's a blended sound.
  • Ute: Sounds like "ute" as in "cute" or "gate." Short ‘u’ sound followed by a ‘t’.

3. Putting it together:

The whole word is pronounced: ˈsʌb.sti.tjuːt

(ˈ means stressed – that’s the syllable you give the most emphasis to)

4. Tips and Considerations:

  • Stress: The stress falls on the third syllable ("-ute").
  • The "ti" sound: The "ti" in "stit" is a single sound, not two separate sounds. Think of it as a quick, tight "t" followed by an "i."
  • Fluidity: It's important to connect the syllables smoothly, rather than pronouncing them distinctly.
