I have always spelled this word wrong. I can’t even think of a phrase to help me remember the “OI” of the word. So I will try a visual image. Singers open their mouths wide to project the words they’re singing. To be a good singer I need to open my mouth so the O for wide mouth and I for I doing this to sing.

We’ll see if this helps me remember how to spell this word.

Do you have a better way to remember? Memorization has never been a strength of mine so I often rely upon other resources.
