between foreign language and their mother-tongue. Especially Indonesian students  who  learn  writing  in  English,  they  get  many  problems  in
composing English because many differences in structure in both English and  Indonesian.  Although  so  many  problems  that  make  the  students  do
errors in writing but the writer only takes the common errors in grammar such as singular plural, word form, word choice, verb tense, add a word,
omit  a  word,  word  order,  spelling,  punctuation,  article  and  meaning  not clear.
1.  Singular and Plural
Talking about singular and plural that means one and more than one. Both English and Indonesian have it. However, the way
they use them is not the same. Usually English add ses in the last of  the word  to  show  a  plural  or  some  word  involve  into  irregular
plural like  knife – knives, child - children. Meanwhile  Indonesian has different pattern to show plural such as by repeating the same
word or by adding the word ‘para’. Example :
E : All the students bring those boxes.
I : Para pelajar membawa kotak-kotak itu.
The difference above make the students get the difficulty in writing to have a very exact meaning without doing any errors. But
the  fact, the  students have a  great enough problem in determining singular and plural.
2.  Article
The  occurrence  of  the  article  varies  depending  upon  the type  of  noun.  The  definite  and  indefinite  article  is  customary  to
recognize  a  zero  article.

The  two  article  are  the  and  a.  Each  of articles  undergoes  a  change  before  a  word  beginning  a  vowel-the
changes  in  pronunciation,  a  changes  in  both  pronunciation  and spelling.

Indonesian does not know the article. And the  students think  that  they  do  not  need  to  use  article  in  writing  an  English
composition.  Eg.  “I  have  big  house’  it  should  be  “I  have  a  big house”.
3.  Addition Word
Sometimes  the  students  miss  several  words  when they  are writing  a  composition.  That  is  why  the  writer  should  add  some
words  to  make  the  students’  composition  complete  when  he  is analyzing  each  students’  writing.  For  example,  “Anton  very
happy”  it  should  be  “Anton  is  very  happy”.  It  is  caused  by  their lack of   grammar knowledge. This error can be seen as a form of
simplification. The simplification is sometimes called “redundancy reduction” because it eliminates many items, which are redundant
to  conveying  the  intended  message.  Redundancy  reduction  makes
