Why Three Systems?
Historical: Kanji came from China (5th century), hiragana evolved from simplified kanji, katakana developed for annotations.
Functional: Each system signals different information:
コーヒーを飲みました。
ko-hi- wo nomimashita.
coffee (katakana) + particle (hiragana) + drink-past (kanji+hiragana)
"I drank coffee."
Looking at this sentence, you immediately know:
- コーヒー = foreign word (katakana → coffee)
- を = grammar particle (hiragana)
- 飲 = main meaning "drink" (kanji)
- みました = grammar ending (hiragana)
