, sociolinguistics is an attempt to find correlations between social structure  and  linguistic  structure  and  to  observe  any  changes  that  occur.  Social
structure itself may  be  measured by  reference to such factors as social class and educational  background;  we  can  then  try  to  relate  verbal  behavior  and
performance to these factors. The most important thing of sociolinguistics lays on the  role  of  social  dialect  which  is  perform  by  speakers  in  a  certain  area  as  it  is
clearly stated from this quotation : The  bulk  of  sociolinguistic  enquiry  falls  under  the  heading  of
performance,  since  it  deliberately  highlights  the  great  heterogeneity within peoples speech. For example, the differences between speakers
caused by dialectal variation are compounded by variation within the speech of a single person, as with the switch from formal to informal
styles,

Basically,  the  scope  of  this  study  is  Sociolinguistics.  It  is  the  study  of relationship  between  language  and  society.  It  explains  why  people  speak
differently  in  different  social  contexts.  It  also  identifies  the  social  functions  of language.  In  sociolinguistics,  the  way  people  use  language  in  different  social
contexts can provide huge information about the way language works, as well as about  the  social  relationships  in  a  community.  We  can  also  know  why  men  and
women  talk  differently  and  why  women  tend  to  be  more  related  to  the  word gossip  than  men.  Actually,  in  all  conversations  people  choose  their  words
carefully  according  to  social  factors  and  social  dimensions  or  in  other  words
social factors  and social  dimensions create different language varieties Holmes, 1992.
According  to  Holmes,  social  factors  here  include  four  things,  they  are participants,  which  deal  with  who  is  speaking  and  who  are  they  speaking  to;
setting  or  social  context  of  the  interaction  where  they  are  speaking  e.g.  home, work, campus; topic, which deals with what is being talked about; function, that
deals with why are they speaking. The social dimensions here include four scales. They are social distance scale concerned with participant relationships whether it
is intimate high solidarity or distant low solidarity, it is useful in emphasizing that  how  well  we  know  someone.  Status  scale  concerned  with  participants
relationships  whether  it  is  superior  high  status  or  subordinate  low  status. Formality scale is related to the setting or type of interaction whether formal high
formality or informal low formality, it is useful in assessing of the social setting or  type  interaction  on  language  choice.  These  scales  are  useful  in  assessing  the
influence of the social setting or type of interaction on language choice. The language used will be influenced by the formality of the setting. The
language choice at a religious service will be very different from language choice on  a  friendly  chat;  functional  scales,  which  relating  to  the  purposes  or  topic  of
interaction,  that  consist  of  two  things,  referential  information;  whether  high information content or low information content and affective solidarity; whether
low  affective  content  or  high  affective  content.  Though  language  serves  many functions,  the  last  two  identified  in  these  scales  are  particularly  pervasive  and
basic. Language can convey objective information of a referential kind, and it can also express the feeling of someone.
