Sentence final particles

From UniLang Wiki

Most final particles are used in Chinese to convey differences that languages such as English often convey by especific expressions or even just by intonation. They can provide information about the speaker's intentions, perspectives, attitude, impressions etc. They are always pronounced in the neutral (fifth) tone, and they're literally the last element to appear in a sentence.

Among the most common particles to be used in Mandarin Chinese, we can highlight the following:

• 吗 — used to mark (neutral) yes-no questions

• �?� — used to suggest and to ask rhetorical questions

• 啊 — used to mark something as obvious

• 呀 — a variation of 啊 that is used when the previous word ends in a vowel

• 呢 — used as a marker of yes-no questions when repeating a question about a different subject, or used to indicate the continuous characteristic of an action / situation

• 嘛 — used to persuade or to emphasize the obviousness

• 啦 — used to indicate doubt, impatience or annoyance

• 喔 — used to indicate surprise, or to emphasize a reminder

• 哦 - used to indicate doubt, or to emphasize a reminder

• 咯 — used to mark something as obvious

As it is easy to realise, such final particles always have the 口 (mouth) radical.
