A common explanation when teaching soo da ‘it appears’ is that it is not used with adjectives such as kirei ‘beautiful’. However, the appropriateness of an expression using soo da is determined not by specific types of adjectives but rather by the context in which it is used. This study reports on the authors’ attempt to teach soo da by contrasting both situations where it is used and those where it is not. The results have shown that this method of teaching significantly improved learners’ understanding of the usage of soo da.
