Is this a comma splice: <Independent clause>, I know

Examples:

  • It's cold, I know.

  • She's awesome, I know.

Are these comma splices? If not, what is the name of the I know clause?

Is there a name for the whole structure?


Solution 1:

When you invert the normal order of the sentence

I know it's cold.

you need a comma to make the sense clear:

It's cold, I know.

So while these appear to be two independent clauses, the first is actually a relative clause with an omitted that. Here is how the sentence would read if we were to put the that back in.

I know that it's cold.

And if we were to invert that, we would have

That it's cold, I know.

But that sounds a little stilted to the modern ear, so we just say

It's cold, I know.

Solution 2:

In those examples, I know is a ‘tail’, a feature of speech which reinforces what is being said.
