If a story, a fear, or an accusation is baseless, it has no facts under it and no good reason to stand on. You use the word to show you disapprove: you are saying the claim should not have been made.

If a story, a fear, or an accusation is baseless如果一個說法、一種恐懼，或一項指控是baseless的 it has no facts under it and no good reason to stand on，就表示它底下沒有事實支撐，也沒有站得住腳的理由。 You use the word to show you disapprove用這個字，是表示你不認同 you are saying the claim should not have been made，你是在說這個說法根本不該被提出來。

A baseless rumour is one nobody can prove; a baseless accusation is an attack with nothing behind it. It is a rather formal, serious word — you will see it in the news, in official statements, and in angry replies, more than in chat between friends.

Though actually, in everyday talk people often just say that is not true or there is no reason for that. Base here means the facts or reasons an idea sits on, not a military base and not first base in baseball.

Though actually, in everyday talk people often just say不過日常說話時大家常常就直接說 that is not true or there is no reason for that『that is not true這不是真的』，或『there is no reason for that這沒有理由』。 Base here means the facts or reasons an idea sits on這裡的base指的是一個想法所依靠的事實或理由 not a military base and not first base in baseball，不是軍事基地，也不是棒球裡的一壘。
