When a fear, rumour, hope, plan, or accusation is ill-founded, it sits on something that is not true, or on reasons too thin to hold it up. You use it about ideas more than about people: an ill-founded rumour, an ill-founded complaint.

When當 a fear恐懼、 rumour謠言、 hope希望、 plan計畫 or accusation或指控 is ill-founded是 ill-founded 的時候， it它 sits on坐在 something that is not true不是真的的東西上， or on或坐在 too thin to hold it up薄得撐不住它的 reasons理由上。 You你 about ideas用在想法上 more than about people多過用在人身上： an ill-founded rumour沒有根據的謠言、 an ill-founded complaint缺乏依據的投訴。

It is a fairly careful, written word; at the dinner table people more often say “that’s not based on anything” or “that’s just a story.” Though actually, calling something ill-founded is a little softer than calling it a lie. It says the ground under the idea is bad, not always that someone meant to trick you.

It它 is是 a fairly careful, written word相當謹慎的書面用字； at the dinner table在餐桌上 people大家 more often say更常說 “that's not based on anything”「那沒什麼根據」 or “that's just a story”或「那只是個說法而已」。 Though actually不過其實， calling something ill-founded說一件事 ill-founded， than calling it a lie比說它是謊話 is a little softer稍微溫和一點。 It它 says說的是 the ground under the idea這個想法腳下的地基 is bad不牢， not always不一定是說 someone meant to trick you有人存心要騙你。

News and school writing like it because it sounds fair: you can admit a worry was ill-founded without calling anyone stupid.

News and school writing新聞和學校寫作 like it喜歡它， because因為 it sounds fair它聽起來公道： you can你可以 admit承認 a worry一個擔心 was ill-founded當時並沒有根據， without calling anyone stupid而不必說任何人笨。
