As far as I know...

"Language is the human capacity for acquiring and using complex systems of communication, and a language is any specific example of such a system."

That's what Wikipedia says, if you ask it for a definition of a "language". But these two simple sentences don't inform us, how important the language is and how it can differ. There are over 6000 languages all over the world. The words are the language's carriers of information. However, here begins one of the greatest problems of humanity - when a word has more than one meaning and when we use specific ways of constructing our utterances. Even if two people speak the same language, they use and form it in different ways. MEN AND WOMAN are a great example of that.

Women tend to describe things with many details and distinguish between shades of colours. What for a woman is pale blue, cornflower, sky-blue, navy-blue, turquoise or azure, is for a man just blue. 

Women often use tag questions, for example: "This film is really boring, isn't it?". It gives their conversation partner a feeling that they're not sure of what they're saying. It seems like they're looking for confirmation of their words which can be perceived as a lack of self-consciousness and may influence negatively the way the men respond to it.

There are some other expressions that are characteristic to women. "As far as I know" is one of them which evokes similar response as tag questions. Using them women tend to hold the person they're talking with responsible for the decisions which are discussed in the conversation.

What is especially winsome about women's language is calling other people honey, sweet-heart, darling, my dear or sweetie. In many cases it shows emotions and feelings (of course, it's sometimes just irony or habit).

Men usually use shorter and conciser sentences. It's more important for them to give only the vital information than to describe things in a very precise way. When they've said everything they were supposed to their job's been done here and from now on it doesn't really matter, if the receiver of their message understood it clearly and in details.

Men don't really use tag questions and expressions similar to that. If they have something to say, they say it with a dot at the end of the sentence. 

An ordinary man speaks more among a big group of people and less when he's in a company of only one person (especially if this person is a woman). He also prefers short jokes or small-talk rather than "confessions" or sharing one's secrets.

Unlike most of women, men prefer not to show their uncertainty. They're also not afraid of saying out loud what they think of something, even if it will cause a fierce discussion or aggression. They're ready to defend their point of view sometimes using unacceptable methods, even if it's wrong and they know that.

Although there are so many differences between language of men and women, they are still able to communicate effectively. Of course, these are all great generalisations, but they probably help us understand other people. Many factors may have influence on how we form the sentences to express our thoughts. It's fascinating that we've found our ways to properly read the hidden information from someone's utterance.
