The word "Colestaff" may seem tricky to spell at first glance. Its pronunciation is /kəʊlstæf/. The "k" sound is followed by an "o" sound, represented by the IPA symbol /əʊ/. Then comes the "l" sound followed by a short "e" sound, like in the word "rest". The consonant cluster "st" is pronounced with a slight pause between the two sounds, followed by a short "a" vowel sound and the consonant "f". Knowing the IPA symbols can help you spell and pronounce words more accurately.
