Definition & pronunciation of interval

Okay, let's break down how to pronounce "interval." It can be tricky for non-native English speakers! Here's a breakdown:

The most common and accepted pronunciation is:

  • /ˈɪntərˌvɛl/

Let's break that down syllable by syllable:

  • ˈɪntər – This is the first syllable.

    • ˈɪn – Say "in" like you would in the word "in." It's a short, crisp "i" sound.
    • -tər – This part is a bit tricky. It's a “tuh” sound, like in "butter." It’s not a hard "t" as in "ton."

  • -vɛl – This is the second syllable.

    • -v – Say "v" as in "van."
    • -ɛl – This is a short "e" sound, like in "bed." Think of the "e" in "bet."

Putting it all together, it sounds like: “in-ter-vel” (with the emphasis on the first syllable: /ˈɪntər/).

Tips for pronouncing it correctly:

  • Stress: The emphasis is clearly on the first syllable ("in-").
  • "tuh" sound: Really try to make the "tuh" sound in the "-ter" part – don't pronounce a hard "t."
  • Short "e": The ending "-el" has a short "e" sound.
