OIoy
OI Diphthong
OI makes the “oy” sound in the middle of a word, like in 'oil' and 'coin'.
How this rule works
A diphthong is a vowel sound that glides from one sound to another. OI glides from “aw” to “ih”. Use OI in the middle of a word and OY at the end.
Remember: OI in the middle — coin and point!
