TWO VARIETY OF A LANGUAGE SITUATED SIDE BY SIDE
THROUGHOUT THE COMMUNITY, WITH EACH HAVING A
DEFINITE ROLE TO PLAY.
IT IS NOT A DIALECT, IF A LANGUAGE IS DIALECT THAT
LANGUAGE WILL NOT BE CALLED DIGLOSSIA.

2. VARIETIES/DOMAIN OF
DIGLOSSIA
• Ferguson’s definition makes a division between a
HIGH (H) variety and LOW(L) variety. Such
varieties are “linguistically related to but
significantly different from one other”.

3. HIGH (H) VARIETY
• H variety is associated with education, government, religious
and other institutional domains.
• It is also the one that standardized form of the historical
language and the one used for writing and scripted
communication.
• It is more seems like high status, seen as a real language,
written with grammar and dictionaries.

4. LOW (L) VARIETY
• L variety use as unrehearsed for daily communication
within the family and in other informal domain of
interaction .
• It is not standardized and shows a wide range of
variation along geographical and socioeconomic lines.
• It is seems like low status, not written, not seen as proper
language.
• It is more likely to use in informal conversation , jokes,
cinema, movies, street and market etc.
