I always want to spell this word with an A rather than an I. The only thing I can think of is using a visual image for this word. If I want to be flexible than one good way to do so, is to lift barbells or hand weights. The little dot over the I can represent a hand weight.

Another possibility would be I want to be more flexIble. Maybe I’ll remember the eye that way

Bad: Flexable

Good: flexIble

If you have a better way to help on the spelling here, please feel free to share in the comment section this blog
