From the data analysis it was found that there was a correlation between vocabulary mastery and speaking skill of grade eight students of MTs Negeri 1 Tanjung Pura with the level correlation value was 0,559 or 55,90 % or on the level of “Fair” Correlation.


INTRODUCTION
The English language is now the most important one to master for travel and business.For this reason, being fluent in English might give an edge in the global marketplace.Students in Indonesia are required to take English classes through high school, and some universities even require students to have a certain score on an English proficiency test before admittance.Learning to speak, read, write, and understand a language requires a wide range of abilities, as noted by (Haycraft, J, 1978).Students need a solid foundation in vocabulary to make progress toward fluency in the other four language skills.
It is impossible to communicate in any way, and without vocabulary, it is impossible to react to what one hears.Without the ability of words to convey anything further, this is the quote that expanding one's vocabulary is vital for learning a language since it helps one become more articulate; communication cannot function effectively without words.Therefore, if kids put in the effort to study, they won't struggle with reading, listening, or writing, and especially won't struggle with speaking.Students will have an easier time improving their speaking abilities if they have a broad understanding of the meanings of a variety of terms.This is because they will be able to effortlessly comprehend what their classmates are saying.After all, they will have mastered the vocabulary.
To speak is to engage in the process of making and conveying meaning through the deployment of a context-specific lexical and symbolic toolkit.The most useful type of oral and aural communication is speaking (Nunan, D, 2003).While (Kathleen M.B, 2005) stated that Speaking is an interactive process of generating meaning that involves producing, receiving, and processing information.This process occurs simultaneously with the act of listening and understanding.Then (Siregar, F. R., 2016) said that Speaking is a type of communication that allows speakers to convey their thoughts, ideas, and emotions to other people through the use of the verbal form.
In point of fact, after speaking with an English teacher from MTs Negeri 1 Tanjung Pura, the reseacher came to the conclusion that.It was brought to her attention that the students' language is still quite bad.The reseacher disclosed that the students had trouble understanding when someone spoke in English to them.Additionally, English teachers found that children had a significant deficit in their ability to memorize words.A very small number of students expressed interest in learning language by heart.Students are notoriously unmotivated when it comes to learning the lexicon of irregular and regular verbs.

METHODOLOGY
The research approach used in this study was quantitative and based on correlation.The correlation statistical test is used to characterize and quantify the relationship between two or more variables in a study conducted using a correlational methodology (John W. Creswell, 2008) The purpose of this method is to determine the degree of similarity between two or more factors.limited or no control over confounding variables in the experiment's design.
The population in this research were eight grade students of MTs Negeri 1 Tanjung Pura.
There were 30 students in total students.15 students from Class B were taken as samples of this study.
This research's instrumentation was a test.Based on (Cameron, L., 2003) theory that encompassed pronunciation, spelling, grammar, and meaning, the speaking test was administered orally, whilst the vocabulary test was administered in writing.The speaking accomplishment test would be compared to the four components of vocabulary mastery that must be assessed.
Fluency, comprehension, vocabulary, pronunciation, and grammar are the five aspects of a speaker's abilities that should be evaluated.Pronunciation should also be considered.The criteria for speaking performance were scaled, and the following indicators were based on those criteria.
(Pandiya, 2003): To know the student's speaking skills in the score the researcher used the following formula as followed : Score = Student Score x 100 Total Score To provide the level-appropriate interpretation of the students' vocabulary mastery and speaking competence scores.The following is how the researcher applied the scale interpretation: In order to conduct an examination of the correlation between the students' degree o vocabulary knowledge and their ability to communicate successfully, the researcher employed the following steps: 1. Determine the score of the correlation by using the SPSS application (rxy).
2. Following the acquisition of the rxy score, the researcher provided an interpretation of the rxy score, as was stated by (Sudijiono, Anas, 2003) as followed
