The fact is that for the effectiveness of suggestion cards, it is important that each card enters only one unknown word. To understand the effectiveness of sentence cards, we must first think about the purpose of studying words. It’s a good idea to write new hieroglyphs when we teach them for the first time, but we don’t recommend writing kanji during your feedback on anki. On the other hand, understanding a word written in kanji is not a guarantee that you can read kanji. If you subtract a sentence with a word that can be written in kanji, but it is not, it may be a good idea to convert it into kanji by hand while you are making the card. In other words, learning the basics of Japanese grammar will greatly improve your ability to understand and learn true Japanese, and in this sense learning grammar is worth it. On the other hand, if you made a card with the phrase “いま暇ある？” on the front side and the English translation “Are you free now?” and the English definition of “暇” on the back side, you would have a much better idea of how “暇” actually works in Japanese. With regular passive and active immersion in Japanese, and constant creation of phrase cards, your understanding of Japanese should continue to improve. If it is a text card, make sure that you can read all the kanji in the sentence. For both text cards and sound cards, there is no need to write part of a sentence, and we advise you not to do this, as it would take too long for your test sessions. The examples of Tae Kim’s sentences will help you consolidate the grammar and vocabulary at the same time. On the back of the kanji cards, you will find the original RTK keyword, some other kanji values, the two most valuable mnemonics on the Kanji Koohii website, and all the “initial element values” listed for this kanji in the original RTK book. On the audio cards, on the other hand, on the back of the card you can see a written sentence form, which has a positive impact on the ability to read. After reading the grammar guide and studying ~1000 of the most common words, you should be more than ready to start studying the sentences, which will be considered in one of the following chapters.
