Complete the word with the right diphthong: oi, oy, ou, ow

Key Notes :

🎯 When two letters blend together to make a vowel sound, that sound is called a diphthong.

🎯 The diphthongs oi and oy make the same vowel sound. At the beginning of a word or in the middle of a word, the oi spelling is usually used. At the end of a word, the oy spelling is used.
