Commentary：
助詞 (
Hiragana: じょし
Romaji: Jo-shi) means a particle, or a marker.
助詞 is a word used in a sentence and never used alone. A particle is placed after another word to indicate the word's status in a sentence. This is because Japanese is flexible in the order of words. Without particles, subject and object of the sentence wouldn't be clear to the listener.
