The purpose of hiragana:
1, marking the pronunciation of Chinese characters;
2. As an auxiliary word;
3. Mix with Chinese characters;
4. The composition of greetings.
The purpose of katakana:
1. Loanwords: proper nouns such as foreigners' names (except Japanese), foreign place names (except Japan) and all loanwords (except Japanese).
2. Onomatopoeia: mimetic language. For example, the dog barks: ワンワン, the cat barks :ニヤーニヤー, the frog barks :ケロケ𞥇𞥇𞥇𞥇𞥇1252525
3. Japanese names of creatures and minerals: (The Japanese government suggests that the names of animals and plants in academic fields should be expressed in katakana, but personal usage habits are not in the specification)
Therefore, hiragana is more used in daily life, while katakana is more used in professional terms and loanwords, not often used.

Japanese architecture
Because the meaning of words is determined by auxiliary words, the word order in Japanese is quite free, but the predicate must be placed last.
Japanese tense
The tenses of Japanese verbs are "past" and "present/future".
Japanese tenses are realized by the change of pseudonyms at the end of verbs. Usually Japanese verbs consist of two parts: stem and suffix. The stems are generally Chinese characters; The pseudonym that constitutes the suffix is called the sending pseudonym (sending name). For example, learning ぶ is a stem and ぶ is a suffix. There are two special verbs-lai (coming) and (doing/doing), and the stem and suffix cannot be separated.
Verbs in modern Japanese all end in a U sound. According to the way of time change, it can be divided into four categories: five verbs (グルー12503I, the first group of verbs), one verb (グルー12503II, the second group of verbs) and カカォ.
One of the verbs can be divided into the former verb and the latter verb. Japanese verbs change regularly except for two kinds of case-changing verbs.
