Should (used for giving direct advice)
Category: Judgment & Opinion
The grammar pattern 'V-dictionary / V-nai + ことだ' is used to give strong advice or suggestions, essentially saying 'the best thing to do is...'. It is directed at a specific person and implies that the action is necessary for a particular outcome. This pattern is often used in situations where the speaker wants to emphasize the importance of a particular action or behavior. The use of 'ことだ' at the end of the sentence gives a sense of finality and emphasizes the speaker's opinion.
