Láadan
Láadan is a feminist constructed language. Its creator was Suzette Haden Elgin. She believed that Western languages were better for saying what men think than what women think. She created the language to make it easier for women to say what they think. For example, Láadan has many words and suffixes for saying how you feel about what you are saying. It also includes words for saying if you know that what you are saying is true, and if so, how.
