The Craft Yarn Council of America standardized abbreviations that appear in patterns to help us have a basic understanding.
To some crocheters, abbreviations are like hieroglyphics and don’t mean anything because they lack understanding on how to use them. Like ancient Egypt with the language on the wall, over time if you study it long enough you will be able to fluently read it.
With pattern reading, the more you read them the more proficient you will get at doing it.
Obviously, crochet terms are not that complicated at Egyptian writing. The point to standardize the terms is to make pattern reading universal. This helps a designer that is just getting started to use language and terms that are understood amongst crocheters.
