其實a.m.或p.m.都是拉丁文

ante是表示：在前，早於的意思；其實英文，也有用這字為字首，表示”在前”的意思，如：antechamber（前廳）；又如關係代名詞的前行詞，就叫做”antecedent”而post是表示：在後，後的意思；如post doc就是”博士後”，而post cold war就是”冷戰之後”，post traumatic stress disorder就是”受傷後緊張症”其實英文是受到拉丁文影響很大

其實a.m.或p.m.都是拉丁文（的縮寫）

而meridiem也是拉丁文，meri是mid的意思，而diem是day的意思，所以meridiem就是noon(midday)的意思

a.m. - ante meridiem (from Latin, meaning "before mid day", or "before the middle of the day")
p.m. - post meridiem (from Latin, meaning "after mid day" or "after the middle of the day").

When you write it, remember there have to be full stops.

a.m. =ante meridiem(=before noon) 上午其實係可以用in the morning

eg:i go to school in the morning.

p.m.=post meridiem 下午..其實可以用at the afternoon

e.g:i have a competition at the afternoon

p.m. =post meridiem 下午
a.m. =ante meridiem(=before noon) 上午

希望幫到你=]
