Translation: "To Say The Least" Looking for a colloquial way to translate: to say the least into Chinese.
Hujiang says:

to say the least的意思是： 至少可以这样说,退一步说
至少可以这样说,退一步说



英语句子
The logic of this was weird to say the least.
至少可以说，这个逻辑推理是奇怪的。

...sounds weird to me....
The next example sentence omits the phrase completely:

The chorus is very catchy to say the least.
副歌部分很容易上口。

Most of the examples of 至少可以说 that I found through Baidu just seem to be translations of English.

What colloquial/natural ways are there to express to say the least in Chinese?
Word for word translations are not always available or desirable. 至少/起码可以说 works, but is foreign in scope. What you want is a phrase that catches the essence of it, like 说得好听, or 毫不夸张地说, or perhaps 坦率地说. 退一步说 is fine, too.

Shorter and more to the point equivalents are 说少 and 少言之.

打折扣地说 and 轻描淡写 both mean understatement, which is another way of phrasing it.
