Speak Your Mind, Or Mind Your Speak

Does LANGUAGE say ideas or does it create ideas?

I am often conflicted when faced with the idea of whether or not language creates your speech and opinions, or whether your opinions are translated into language. I have always believed that language, be it any dialect, changes how what we say is communicated to others. I also believe that our thoughts are changed to fit the descriptions and restrictions that words and grammar provide. It is always difficult to find the perfect word that describes exactly what you are thinking. Not to mention, words have different meanings when translated. In some cultures, certain words have more emphasis in the native language than in others, as well as some words have double meanings. But sometimes words are just used to express the original idea you have, and if it you think of the process of turning your thinking into words as translating it into language, it just means that although some of the words may not fully express the idea you are trying to stress or communicate, it does keep the original message you had. And it is more effective on changing your ideas when communicating with others, as you can easily create meanings for non-existant words and still know what you are saying, while others will have no idea of what you are talking about. So language, rather than changing the ideas, changes the way we communicate them, and how our ideas are percieved by others. At least, that's what I think.
