7 Make the discourse hang together so that people could follow what you are
saying. Specific languages could be more or less difficult to learn, depending on how
different or similar they are to the languages the learner already knows. Therefore, speaking skills which consist of five aspects such as grammar, vocabulary, fluency,
pronunciation, and task or content should be improved to make the speaking process better.
2.2.2.1 Grammar
There are various definitions of grammar. Different experts define the term grammar differently. Harmer 2001:12 argues “the grammar of a language is the description of
the ways in which words could change their forms and could be combined into sentences in that language.” From the definition, I could conclude that if people know
the grammar of their language, they also know how the language is used, and they know how to construct sentences or utterances in the accepted forms.
2.2.2.2 Vocabulary
Vocabulary is a total number of words which make up a language, vocabulary also words known to or used by person in trade, profession, etc. Mastery in vocabulary is
a complete control of knowledge. It could be said that the arrangement of words into a sentence is a part of vocabulary. Student who wants to succeed in language learning
process has to master the components of the language. One of them is vocabulary.
2.2.2.3 Comprehension
Comprehension is the ability to understand something. In speaking skill students must master the comprehension of the sentences. It is to understand what the speaker says
and get the point of information related to the topic discussed.
2.2.2.4 Fluency
Speaking English fluently is a goal of many learners of English. Fluency means being able to communicate your idea without having to stop and think too much about what
you are saying. According to Weir 1993:42, fluency is smoothness of execution, ability to negotiate meaning and ability to use communication strategies with ease
when it is difficult. In other words, it could be said that fluency is very important because without having it, communication is less perfect and sometimes it is difficult
to convey message.
2.2.2.4 Pronunciation
Pronunciation usually deals with the speech sound that is produced by speakers. Ramelan 1994:2 suggested that “differences in pronunciation between one speaker
and another are caused by geographical, social and historical factors; or they may be caused by individual peculiarities such as stuttering, lisping, or other speech
deficiencies.” From that statement, Indonesian speakers who have different geographical with America or England as the native speaker of English, have
difficulties in pronouncing English word, therefore Indonesian students need to learn harder in pronouncing English words in many ways.
2.2.2.5 Task or Content
