...SOCIOLINGUISTICS...

1. I think the relationship between society and language is the important conection which has to be between both, I mean it is necesary to exist a language in a society because is the most important thing in order to communicate each others. so, it doesn´t matter if we communicate in an oral or written or corporal way, the important thing here is the language that is our code in each community or society.

2. Well because it depends on the costums of each community, I mean there aren´t the same needs in a place or region which is near the sea with other which is in the centre of the country and with a cold weather. So, for me it depends on the needs of each community and the costums of them.

3. I think everything affects the way we speak, the food, the weather, the music, everything changes according to the needs and the place of each group or community.

4. An accent is the way that particular person or group of people sound.  It’s the way somebody pronounces words, the musicality of their speech, etc.

A dialect describes both a person’s accent and the grammatical features of the way that person talks.

5. An overt prestige dialect is generally one that is widely recognized as being used by a culturally dominant group. In England, this would be RP. In the US, the Midwestern standard. 

A covert prestige dialect, on the other hand, is one that is generally perceived by the dominant culture group as being inferior but which compels its speakers to use it to show membership in an exclusive community.  (http://answers.yahoo.com/question/index?qid=20071106190328AAIeYQI)

Pidgin language  is nobody's native language; may arise when two speakers of different languages with no common language try to have a makeshift conversation. Lexicon usually comes from one language, structure often from the other. Because of colonialism, slavery etc. the prestige of Pidgin languages is very low. Many pidgins are `contact vernaculars', may only exist for one speech event.

Creole  is a language that was originally a pidgin but has become nativized, i.e. a community of speakers claims it as their first language. Next used to designate the language(s) of people of Caribbean and African descent in colonial and ex-colonial countries (Jamaica, Haiti, Mauritius, Réunion, Hawaii, Pitcairn, etc.) (http://ccat.sas.upenn.edu/~haroldfs/messeas/handouts/pjcreol/node1.html)
