Definition & pronunciation of costly

costlyadjective

/ˈkɒstli//ˈkɔːstli/

Okay, let's break down how to pronounce "costly" in English. Here's a breakdown and a few ways to approach it:

1. The Core Sounds:

  • "Cost": This part is fairly straightforward. It sounds like "coast" – like the ocean. The "o" is a short "o" sound, like in "hot."
  • "ly": This is a suffix that adds a "-ly" to the end of a word, making it an adverb (describing a way of doing something). The "ly" itself makes a soft "l" sound, similar to the "l" in "light."

2. Putting it Together – The Primary Pronunciation:

The most common and generally accepted pronunciation is:

  • ˈkɒst.lɪ

Let’s break that down further:

  • ˈkɒst: Stress is on the first syllable ("cost"). The "o" is a short "o" sound (as in "hot"). The "st" is pronounced as one syllable.
  • lɪ: This is a very short, quick "i" sound – like the "i" in "bit".

3. Phonetic Transcription (for accuracy):

You might see this written phonetically: /ˈkɒst.li/

  • ˈ - This symbol indicates primary stress.
  • k - as in "kite"
  • ɒ - a short, rounded "o" sound (like in "lot" or "caught")
  • s - as in "sun"
  • t - as in "top"
  • l - as in "light"
  • ɪ - a short, quick “i” sound (like in "bit")

4. Tips for Pronunciation:

  • Don’t over-emphasize the “l”: The “l” in "costly" is very quiet and quick. It’s not a strong, emphasized "l" like in "light."
  • The "o" is short: Avoid making the "o" in "cost" sound like a long "o" as in "boat."
  • Listen to Native Speakers: This is the BEST way to learn! Search online for “how to pronounce costly” on YouTube or use a dictionary website like Merriam-Webster or Cambridge Dictionary that has audio pronunciation. Hearing it will really help you get the rhythm and intonation right.
