Arguably the most important part of a Cutie Mark is the Glyph, here meant to refer to the image depicted. It is from this that we gain the most significant indication of a pony's talent. That said, there is a fair amount of interpretation involved in reading Cutie marks. For example, Cheerilee's Cutie Mark, a Triune of Smiling Daisies is meant to represent her skill and passion for teaching. She described the mark in the episode "Call of the Cutie"

Quote

I had decided to become a teacher, and the flowers symbolized my hope that I could help my future students bloom if I nurture them with knowledge. The smiles represented the cheer I hope to bring to my little ponies while they were learning."

What this tells us is that apart from the pure symbolism inherent in the Cutie Mark, a pony's personal understanding of it can play a significant role as well. This presents us with a bit of a Dilema. Using the system that I have devised would not give us the best understanding of a mark like Cheerilee's. The question then is this; How do we handle the subjective meanings of Cutie Marks?

One possibility would be to simply disregard this aspect of Cutie Mark Interpretation as it makes the entire exercise a foregone conclusion if you already have an idea of what a Cutie Mark means. In it's capacity as a tool for character creation, this would be a perfectly tenable solution, but in it's secondary purpose of reading meaning from existing marks, this falls short. I recognize that it would be impossible to systematically derive the subjective meaning from a mark so I'm still left with the question of how to do it.

As always, your input is welcome and encouraged.
