Accidental gap

Imagine you are playing with your toy blocks, and you are trying to build a tower. You stack the blocks on top of each other and make sure they match and fit perfectly. But then, you accidentally drop a block, and there is a little space in between two blocks.

That space is called an accidental gap. It means that there is a small hole or opening where there should not be one. In other words, something was supposed to fit in there, but it didn't because of the accidental gap.

Now imagine that the blocks are actually words, and you are trying to read a sentence. The sentence is a bunch of words put together to make sense. But if there is an accidental gap, it means one of the words is missing, and the sentence doesn't make sense anymore.

This is why it's important to pay attention and make sure everything matches up and fits together correctly. Accidental gaps can cause confusion and make things not work the way they should.
