Definition & pronunciation of diagnostic

diagnosticadjective

/ˌdaɪəɡˈnɒstɪk//ˌdaɪəɡˈnɑːstɪk/

Okay, let's break down how to pronounce "diagnostic." It's a tricky one! Here's a breakdown with phonetic guide and tips:

Phonetic Transcription (IPA - International Phonetic Alphabet):

/ˌdaɪ.æɡˈnɒ.s.ɪs/

Breakdown:

  • ˌdaɪ: Like "dye" (as in the color dye). The "ˌ" symbol indicates a secondary stress.
  • æɡ: Similar to "ag" in "again". It’s a short, open ‘a’ sound.
  • ˈnɒ: This is the stressed part. “n” as in “no,” and “ɒ” (pronounced like the “o” in “hot” or “lot”). It’s a rounded vowel sound.
  • sɪs: Like "sis" in "sister".

Putting it all together, it sounds roughly like:

"Dye-ag-noun-sis"

Tips for Pronunciation:

  • Stress: The primary emphasis is on the second syllable ("nɒ"). This is key!
  • "ag" sound: Don’t make it a long “a” sound like in “apple." Keep it short and quick.
  • "ɒ" vowel: This is the most challenging part for many learners. Practice saying “hot” and “lot” repeatedly to get the mouth shape right. Try to round your lips slightly.
