Polysemy  is  one  of  those  complex  phenomena  in  the  study  of  meanings. Polysemous  words  can  have  several  meanings  and  it  is  rather  complicated  to
know each meaning only by holding onto one possible meaning. An  individual  word  has  a  meaning  and  words  in  phrases  and  sentences
have meanings as well. Therefore, the major division of semantics is between the study of the meanings of words, namely lexical semantics, and the study of word
meanings  to  determine  the  meaning  of  phrases  and  sentences,  namely compositional semantics.
a. Lexical Semantics
Lexical  semantics  is  the  study  of  meaning  in  a  word  level.  Lexical semantics describes the meaning representation of every word in the language and
the  relations  among  the  meanings  of  the  words  in  the  language  Saeed,  2003. Cruse 2006 defines lexical semantic as the study of “the meaning of words; the
focus here is on ‘content’ words like tiger, daffodil, inconsiderate, and woo, rather than  ‘form’’grammatical’  words  like  the,  of,  than,  and  so  on”  p.  15.  Content
words  are  words  that  can  stand  alone  and  have  already  had  their  own  meaning while form  or grammatical  words are words that have a function in  grammatical
constructions  of  phrases  or  sentences.  Pustejovsky  1995  gives  more  specific definition  of  lexical  semantics  as  “the  study  of  how  and  what  the  words  of  a
language denote” p. 1. In  short,  lexical  semantics  studies  the  meaning  of  an  individual  word.
Thus,  lexical  semantics  deals  with  the  collection  of  words  or  lexicon.  The common way to find the meanings of a word is by looking it up in the dictionary.

Another way to find meanings of a word is by analyzing the semantic features of words that is
“conditions that must be met in order for a word to be appropriate to use”  Bergmann,  Hall,    Ross,  2010,  p.  246.  For  example,  the  word  stallion
which  refers  to  a  male  horse  has  the  semantic  features  as  [+animal]  [+mammal] [+horse]  [+male].  Those  features  show  that  the  stallion  is  not  a  mare  which  is  a
female horse, or it is not a dog which is not a horse. The relation among words also determines the meaning of the word. Some
examples of word relations are hyponymy the meaning of words that is included in  other  word  meanings,  synonymy  words  that  have  the  same  meanings,  and
antonymy words that have the opposite meanings. This study will investigate the polysemy phenomenon where a single word
has  several  meanings.  Geeraerts  2010  claims  that  polysemy  is  the  result  of  the fact  that  meaning  is  changed  when  language  is  used  in  new  situations  and
contexts.  Multiple meanings, such as polysemy,  happen under this circumstance. Thus, lexical semantics is also used to study polysemy as it also deals with a word
that has multiple meanings.
