<p>是 does not mean &quot;is&quot; here. The reason is that the &quot;is&quot; required here is already contained in &quot;解决了&quot;. The skeleton of this sentence is &quot;事情解决了&quot;, that is, &quot;解决了&quot; is itself a verb and can be translated to &quot;is resolved&quot; or &quot;has been resolved&quot;. No one would ever say &quot;事情是解决了&quot; to mean &quot;the problem has been resolved&quot; (for this sentence to make sense it must mean something complete different, I'll.mentioned it later).</p>

<p>Notice that, the reason I say 是 does not mean &quot;is&quot; here is that, if it did mean &quot;is&quot;, then after stripping the original sentence of unnecessary parts, you should still get a correct sentence without altering the basic meaning of the original sentence.

<p>你今天<strong>到底是</strong>有什么毛病？ = What <strong>the heck</strong> is wrong with you today?</p>

<p>Here 到底是 goes together and 是 does not mean &quot;is&quot; because 有 is already the verb. A word for word translation is</p>

<p><strong>Exactly</strong> what problems do you have today?</p>

<hr />
<p>Finally let me remark on the sentence 事情是解决了. I said before that it is not a correct sentence to express &quot;the matter has been resolved&quot; because 是would be a redundant verb. But it can be a correct sentence if you interpret 是 as &quot;although&quot;, for example,</p>

I think this idea that it prevents 到底 and 解決 from being stuck together is interesting, because if I hear "這件事情到底解决了" I half expect a "沒有" to follow as a question: "Did this matter ever get resolved or not?"

<p>Simply speaking, '是' is equivalent to "is", and '了' is often used in perfect (or past) tense.</p>

<p>So, it means "is (是) eventually resolved (解决了)".  If one sentence ends with "了", it often tends to describe a state of a thing.</p>

I feel that the origin should be 这件事情到底(還是)解决了, which you might have an easier time to understand 是's role, yet what you had there is more commonly seen in modern Chinese.

是 does not mean "is" here. The reason is that the "is" required here is already contained in "解决了". The skeleton of this sentence is "事情解决了", that is, "解决了" is itself a verb and can be translated to "is resolved" or "has been resolved". No one would ever say "事情是解决了" to mean "the problem has been resolved" (for this sentence to make sense it must mean something complete different, I'll.mentioned it later).

In the sentence

Clearly, you can replace 到底 here by 到底是 or 到底还是.

Without the 是, the sentence may be mistaken for a question.
