Japanese particles

Japanese particles, joshi (助詞) or teniwoha (てにをは), are suffixes or short words in Japanese grammar that immediately follow the modified noun, verb, adjective, or sentence. Their grammatical range can indicate various meanings and functions, such as speaker affect and assertiveness.

Orthography and diction

Japanese particles are written in hiragana in modern Japanese, though some of them also have kanji forms (弖 or 天 for te て; 爾 for ni に; 乎 or 遠 for o を; and 波 for wa は). Particles follow the same rules of phonetic transcription as all Japanese words, with the exception of は (written ha, pronounced wa), へ (written he, pronounced e) and を (written using a hiragana character with no other use in modern Japanese, originally assigned as wo, now usually pronounced o, though some speakers render it as wo). These exceptions are a relic of historical kana usage.

Types of particles

There are eight types of particles, depending on what function they serve.
