Japanese Nai-Form Quiz: Practise Plain Negative Verbs
The nai-form is a plain negative verb form. You will meet it in negative statements, prohibitions and patterns that ask someone not to do something. These ten questions focus on forming the verb correctly rather than choosing a translation from a list.
Before you start
For ichidan verbs, remove る and add ない. For godan verbs, move the final sound to the a-row before ない. A verb ending in う needs わない, as in 買わない. The irregular forms are しない and 来ない, with the latter read こない. The ordinary plain negative of ある is ない.
Do not change a verb into its masu stem and simply attach ない: 読みない is not the plain negative of 読む. Check the recorded group, write the form from memory, then compare it with the explanation. Accepted kanji and kana spellings are shown when you review.
