Definition & pronunciation of perforation

perforationnoun

/ˌpɜːfəˈreɪʃn//ˌpɜːrfəˈreɪʃn/

Okay, let's break down how to pronounce "perforation." It's a tricky one! Here's a breakdown with audio cues if possible:

1. Syllables:

The word is divided into three syllables:

  • per - like the word "pear"
  • a - as in "apple"
  • -for - like the word "for"
  • -a - as in "apple"

2. Phonetic Breakdown (Using IPA - International Phonetic Alphabet - this is the most accurate):

  • /pə/ˈrɒrɪʃən/

Let's break that down:

  • /pə/ - Pronounced like "per" as in "perceive." The "ə" is a schwa sound, a very short, unstressed vowel.
  • /ˈrɒrɪ/ - This is the trickiest part! The stress is on the second syllable. It's pronounced like this:
    • /rɒ/: The "r" is a strong, rolled "r" (if you can do it - it's more common in British English).
    • /rɪ/: Like "ree."
  • /ʃən/ - Pronounced like "shun" as in "sun."

3. Putting it Together (Approximate English Pronunciation):

"Per-a-FOR-a-shun"

Tips & Considerations:

  • The "r" sound: As mentioned, the rolled "r" is common, especially in British English. If you can't roll your "r" perfectly, it's still understandable. Just make sure it's a clear "r" sound, not a soft "d" sound.
  • Stress: The stress is on the second syllable ("FOR"). Get the emphasis right!
  • Smoothness: Try to link the syllables together smoothly. Don’t pronounce each syllable too distinctly.
