Definition & pronunciation of corrosion

corrosionnoun

/kəˈrəʊʒn//kəˈrəʊʒn/

Okay, let's break down how to pronounce "corrosion" in English. It can be a tricky one! Here's a breakdown:

1. Syllables: The word is divided into three syllables:

  • cor - (like "core" - the center of something)
  • robs - (rhymes with "jobs" or "obs")
  • tion - (rhymes with "motion" or "mention")

2. Sounds:

  • cor: Pronounced like "core," with a short “o” sound.
  • robs: This is the tricky part! It’s pronounced with a “b” sound, but it’s often softened or nearly silent. Think of it as more of a “ruh” sound blending into the “bs.” Some speakers will actually drop the 'b' completely, especially in American English.
  • tion: As mentioned, rhymes with "motion" or "mention."

3. Putting it Together:

It's roughly pronounced as: KOR-rohbs-shun

Here's a helpful breakdown and tips:

  • Stress: The primary stress is on the first syllable: COR.
  • The 'b' in 'robs': Don't overemphasize the 'b'. It's subtle. It's more of a glide into the “bs.”
  • "Shun" at the end: Pronounce this clearly as in “motion” or “mention”.
