Sentence-final particle

Sentence-final particles, including modal particles, interactional particles, etc., are minimal lexemes (words) that occur at the end of a sentence and that do not carry referential meaning, but may relate to linguistic modality, register or other pragmatic effects. Sentence-final particles are common in Chinese, including particles such as Mandarin le 了, ne 呢, ba 吧, ou 哦, a 啊, la 啦, ya 呀, and ma 嗎/吗, and Cantonese lo 囉 and ge 嘅. These particles act as qualifiers of the clause or sentence they end. Sentence-final particles are also present in Japanese and many East Asian languages, such as Thai, and especially in languages that have undergone heavy Sino-Tibetan influence, such as the Monguor languages.
