Definition & pronunciation of tube

Okay, let's break down how to pronounce "tube" in English. There are actually two common pronunciations, and it depends on what you're referring to:

1. "Tube" (as in a subway/underground train):

  • Pronunciation: /ˈtuːb/ (rhymes with "boob")
  • Breakdown:
    • ˈtuː – This part is a long "oo" sound, like in "moon" or "blue". It’s a deeper, fuller sound than the short "oo" in "book".
    • b – A simple "b" sound.

2. "Tube" (as in a paper tube or a cylindrical object):

  • Pronunciation: /tuːb/ (rhymes with "cube")
  • Breakdown:
    • /tuː/ – This part is a short "oo" sound, like in "book" or "foot".
    • b – A simple "b" sound.

Here's a quick way to remember the difference:

Tips for Using “Tube” Correctly:
