In my opinion, language can reveal cultural attitudes towards women. For example, the Japanese language shows attitudes towards women in the derivations of some words used to refer to family members. The character for "husband" is one that means "lord" or "master." By contrast, words for wife mean things like "inside the house." This clearly shows what is expected of women.
Language can help sustain attitudes as well. For example, in English, we tend to always use the pronoun "he" to refer to a person in the abstract. We refer to human beings as "men." You can argue that this encourages us to think of men as the "true" people and women as sort of afterthoughts.
