1. Introduction The theory of Brown and Levinson in Politeness
extensively uses as basic research by researchers in
the field of not only in linguistics but also in
Economic, Psychology, and so on. In the last three
decades, the research on politeness strategies has
increased significantly in terms of social and
linguistic aspects. It is evident which comes from the
various papers appear on the issues in the
international journals and monographs. The politeness
strategy proposed by Brown and Levinson (1987) for
oral discourse can be applied to interpret the scientific
culture of scientific writing. Brown and Levinson
developed a theory to explain phenomena related to
the politeness on verbal communication and non-
verbal communication.
In general, people usually behave in everyday
interactions because they care about their public self-
image. According to Brown and Levinson (1987), the
act of maintaining a face in pragmatic courtesy
includes actions that threaten faces and actions to save
faces. Following the theory of politeness, a face
consists of two related elements: a positive face and a
negative face. A positive face is defined only as a
'self-image' while a negative face is the desire to have
freedom. Besides, Leech (1983) has proposed the
concept of modesty itself through a set of principles.
Indeed, this is a way to explain how politeness
operates in conversation exchange. Brown and
Levinson's Politeness Theory also outlines four main
types of politeness strategies that include baldness on
record, negative politeness, positive politeness, and
not being noted. These strategies are used to express
messages to save the listener's face when facial
actions are desired. In communication, there is two-
part. The first of all is verbal communication, and the
second is non-verbal communication (Weaver, R., &
Hybells, S. 2007).
Verbal communication can be seen by way
perspective of linguistics features, namely length of
speech, speed of expression, loudness, etc. For
example "Where are you going?” its can expressed
differently depending on who the speakers is, to
whom them speaks, on what occasion the utterance is
expressed and so on (Mujiyanto, Y. 2017). For
another example like the word “Be Quiet!” this is a
polite word when parents tell their children to be quiet
in certain situations. But this word would be
impoliteness if the children were telling their parents
to be quiet. Verbal communication can also be
calculated
from
a
socio-cultural
perspective
background such as the face, strength, status, age,
gender, social distance, kinship, participant role, and
discussion in the talk community.
