The word "KLY" may seem simple, but its spelling can be confusing. The correct pronunciation is /klaɪ/, with a long "i" sound. This can be tricky because the "y" at the end might suggest a shorter vowel sound. However, the "y" in this case acts as a vowel, and when it follows a consonant, it usually creates a long vowel sound. So, when spelling "KLY", remember to use a "y" and not an "i" to create that long "i" sound.
