In English, "知道了" can be translated as "I understand" or "Got it." This phrase is commonly used to indicate that someone has understood something that was explained to them.

The origins of this phrase are not clear, but it is likely derived from the verb "知道," which means "to know" or "to be aware of" in Chinese.

Here are some examples of how "知道了" can be used in English:

"知道了，我会尽快处理这个问题。" ("Got it, I'll take care of this issue as soon as possible.")

"知道了，我明白了。" ("I understand, I get it now.")

"知道了，谢谢你的提醒。" ("Got it, thank you for the reminder.")
