This paper reports the research results on how to describe adverbs with similar meanings and are difficult to distinguish between, and examples of their usage in Japanese monolingual dictionaries for learners. It is very difficult to show how to distinguish the usage of synonyms by annotation in a small dictionary of this kind. The research results indicate, however, that showing vocabulary and expressions that co-occur in the descriptions of the glossary and examples may help learners when they are not sure which of the similar expressions they should use.
