This document discusses some key aspects of Japanese grammar and verbs. It notes that context is important in Japanese as a grammatically complete sentence only requires a verb. It also explains that Japanese verbs always come at the end of sentences in the subject-object-verb order. The document classifies Japanese verbs into ru-verbs, which end in -ru, and u-verbs. While most u-verbs do not end in -ru, some ru-verbs are actually u-verbs depending on the vowel sound before the -ru ending. Examples are provided to illustrate these points about Japanese verb classification and word order.
