Japanese grammar

86 compact cards using familiar vocabulary from your study list. Each has a pattern, three example rows and one useful caution. AI generated from learning materials.

Covers the 29 topics visible in your Busuu grammar screenshot, the 32 Anki grammar items, and supporting grammar from reviewed lessons. Overlaps are merged. This is a revision reference, not a claim that you can recall every form.

“Casual” uses everyday plain forms; “polite” usually means です/ます. Respectful and humble language depends on whose action you describe. Anime-style endings are labelled separately. A slash shows alternatives; an arrow shows a change of form.

Open one card at a time, or pick a section below. The vocabulary drawer gives meanings from your recorded list; example spellings and conjugations may differ from those records. Hover over or tap Japanese words in examples, patterns and vocabulary for romaji and a Jisho link. Keyboard: focus a word and press Enter; Escape closes the popup. Long vowels use spellings such as ou and ei. No recall tests yet.
