System Mood of Grammar

A proposition is something that can be argued in particular way. When there is an information exchange, it means arguing whether something IS or IS NOT. Modalization is always expressing the implicit judgment of the speaker because it is the way the speaker getting into the text expressing a judgment about certainty, likelihood, or frequency of something happening or being. The expressions of modalization can cover mood adjunct and modal auxiliaries. Modalization involves the expression of probability and usuality. Modalization involves the expressions of i probability and ii usuallity. Eggins 1994:179 argues that probability is where the speaker expresses judgments as to the likelihood or porbability of something happening or being. Usuality is where the speaker expresses judgments as to the frequency with which something happen. a Probability It occurs when there is an expression of judgments to the likelihood or probability of something happens. Eggins 1997:100 ranges the degrees of probability from “high” which means almost certain to “low” that means very uncertain it can be. It can be illustrated as follows. Table 02: The Degree of Probability Expression Degree He eats two apples. positive polarity He must definetely eats two apples. modalized: high probability He may perhaps eats two apples. modalized: medium probability He might possibly eats two apples. modalized: low probability Source: Eggins 1997:100 b Usuality It occurs when there is an expression of judgments to the frequency of something happens. Eggins 1997: 102 ranges the degree of usuality from “high” that means always done to “low” which means never done or almost never done. It can be illustrated as follows. Table 03: The Degree of Usuallity Expression Degree He plays badminton. positive polarity He always plays badminton. modalized: high usuallity He usually plays badminton. modalized: medium usuallity He sometimes plays badminton. modalized: low usuallity Source: Eggins 1997:102 Both probability and usuallity can be expressed in some three ways: I. By a finite modal operator in the verbal group That will be my car. II. By a modal adjunct of probability or usuallity That is probably my car. III. By both together That will probably my car.
