Definition & pronunciation of cluster

clusternoun

/ˈklʌstə(r)//ˈklʌstər/

Okay, let's break down how to pronounce "cluster" in English! It's a tricky one for learners. Here's a breakdown with different approaches:

1. The Most Common & Generally Accepted Pronunciation (American English):

  • ˈklʌstər (This is the one you'll hear most often in the US)

    • ˈklü - Think of the "klü" sound like "clue" but with a slightly more rounded and forced "u" sound. It's almost like you're trying to push the vowels out a little.
    • stər - This is a short "t" sound, followed by an "er" sound, similar to “stir” or “butter.”

2. British English Pronunciation:

  • ˈklʌstə (Notice the missing second "r" at the end)

    • ˈklü - Same as above.
    • stə - Same as above.

Key Tips & Breakdown:

  • The “cluster” sound: The difficulty lies in the initial consonant cluster – “cl” followed by “str.” You need to pronounce each sound distinctly while keeping your mouth moving as if you were saying one word.
  • Rounding the lips: For the “klü” sound, slightly round your lips as if you were going to whistle, but don’t make a whistling sound. This gives it that "forceful" quality.
  • Don't blend: Avoid trying to blend the sounds together smoothly, especially at first. Think of saying “cl” and then “str” separately.
