If you reiterate a statement or an opinion, you say it again, on purpose, so that nobody can miss what you mean. A leader reiterates a promise. A teacher reiterates a rule. The word is more formal than say again, and you hear it in speeches, meetings, and news: a speaker will reiterate that the hospital will stay open.

Though actually, it can sound a little heavy, even a little impatient — as if the speaker thinks people did not listen the first time.

Students sometimes reach for it in a message to a friend, where just to be clear would sound more natural.

The old Latin is almost funny: re- already means again, and iterare already means to repeat, from iterum, again — so the word is built with again twice.

The old Latin古老的拉丁字源 is almost funny幾乎有點好笑：re- already means again re-本身就已經是「再」的意思，and iterare already means to repeat而iterare本身就已經是「重複」的意思，from iterum, again來自iterum，也是「再」的意思——so the word is built with again twice所以這個字等於把「再」重複用了兩次。
