Roots of Calligraphy is coming from ancient Greek and means beauty + 
writing. It is a variation of visual arts. It can also be called fancy 
writing or lettering. A good explanation of calligraphy is ”the art of 
giving form to signs in an expressive, harmonious and skillful manner” 
(Mediavilla 1996: 18).
This is the tool that calligraphers use.

Also graffiti is another subhead of calligraphy which is created much
 more later then other calligraphies. It has been created in the 1960s 
by writing (violating) to public to private property. Graffity always 
seemed as anarchist, destruction based and vandalism to society but in 
artist vision it has called passionate art which feeds the soul of 
todays expressionism. Eventhough graffiti and calligraphy share similar 
attributes still they are comin from different regions of communities 
and cultures.
