Definition & pronunciation of unreliable

unreliableadjective

/ˌʌnrɪˈlaɪəbl//ˌʌnrɪˈlaɪəbl/

Okay, let's break down how to pronounce "unreliable" in English. Here's a phonetic breakdown and a guide to help you:

Phonetic Transcription (IPA - International Phonetic Alphabet):

/ʌnˈraɪəbəl/

Breakdown:

  • ʌn: This is like the "uh" sound in "but" or "sun." It’s a short, open vowel.
  • ˈraɪ: This is the stressed syllable. Pronounce "ry" as in “ride.” This is the core of the word.
  • əbəl: This part is a bit trickier. "ə" is a schwa sound—a very short, neutral vowel sound, similar to the “a” in “about.” "bəl" is pronounced as you would typically say "b" and “l”.

How to Say It Aloud (Step-by-Step):

  1. Start with: "uh" (like in "but")
  2. Add: "ry" (as in "ride") – make sure to give this syllable a little more emphasis.
  3. Follow with: schwa "ə" – a very quick, relaxed "uh" sound.
  4. Finish with: "bəl" – as in “bulb.”

Putting it together:

Un- ry-a- ble

Tips for getting it right:

  • Stress: The emphasis is clearly on the second syllable ("ry"). This is crucial.
  • Schwa: Don't try to pronounce the “ə” sound with much effort. It's meant to be subtle and relaxed.
  • Listen to Examples: The best way to learn is to hear it said correctly. Search for "how to pronounce unreliable" on YouTube or Google Audio to hear native speakers.
