CHAPTER II REVIEW OF RELATED LITERATURE
This  chapter  consists  of  two  subchapters:  theoretical  description  and theoretical framework. Theoretical description presents the theories related to this
study matter. Theoretical framework discusses all of the major relevant theories to assist the researcher in answering the research problems.
A. Theoretical Description
Theoretical  description  gives  a  clear  description  of  the  theories  related  to the  topic  of  this  study.  It  presents  theories  about  word  classes,  semantics,
synonymy, corpus linguistics, the role of collocation, and previous corpus studies.
1. Word Classes
Word classes or parts of speech or lexical categories are a set of language categories  for  classifying  words  Bloor    Bloor,  2004.  There  are  eight  word
classes  in  English:  verb,  noun,  adjective,  adverb,  determiner,  preposition,  and conjunction.
a. Verb
Verb is  a  word class  which contains  words referring to actions  Davies Elder, 2006. According to Davies and Elder 2006, in English, verbs are used for
tense  marking.  Consider  these  sentences:  1  John
eats
three  apples;  2  Jean
walked
home. Those sentences  have the endings,
-s
and
-ed
in  the verbs
eat
and
walk.
The endings after the verbs are named
inflections
Aarts, 1997
.
Inflections
12 express grammatical properties. The
–
s
ending in
eats
indicates that the verb is in the present tense, so that it is called a
present tense inflection
Aarts, 1997. Aarts 1997 adds that the
–
ed
ending shows that
walked
is in the past tense, therefore it is called a
past tense inflection
. According to Aarts 1997, there are two forms of verb:
finite verb
, a verb which  takes  tense;  and
nonfinite  verb
,  a  verb  which  does  not  take  tense.  The example of finite verb is in this sentence,
He painted the wall
. The finite verb of that  sentence  is
painted
.  Next,  the  example  of  nonfinite  verb  presented  in  this sentence,
She loves singing
. The word
singing
is nonfinite verb of that sentence. Verbs  can  be  differentiated  by  how  many  nouns  arguments  they  are
connected with. Based on Davies and Elder 2006, there are three types of verb: intransitive, transitive and ditransitive. Intransitive is a verb which only takes one
argument.  Take  for  instance,  in  the  sentence,
Peter  died
.  The  verb
died
is intransitive  because  it  takes  only  one  argument,
Peter
.  According  to  Carstairs- McCarthy 2002, intransitive verbs are verbs which lack such an object. Take for
instance, in
Tex studies
,
Tex
is a subject and
studies
is a verb, which describes the action what the subject does. There is no more information about what the subject
studies. The second type of verb is transitive. Transitive is a verb which takes two
arguments Davies  Elder, 2006. For example in a sentence,
The hunter kills a wolf
.  The  verb
kills
has  two  arguments,  which  are
the  hunter
and
a  wolf.
Therefore,  the  verb
kills
is  transitive.  Carstairs-McCarthy  2002  adds  that transitive  verbs  or  verbs  which  are  used  transitively  are  ones  with  an  „object’
