The modern Japanese writing system combines logographic kanji and syllabic kana, consisting of hiragana and katakana, creating a complex structure with thousands of kanji and two main phonetic scripts. Kanji represents most content words, while hiragana is used for grammatical elements and inflections, and katakana is reserved for foreign words and emphasis. Unique writing mechanisms such as jukujikun and ateji further illustrate the intricate nature of Japanese writing, as well as differences in sentence structure and grammar compared to English.
