the trouble is that?

[cyber_man]

Hi to all,
I have a question about an idiom.What does mean "The trouble is that"?

[Anglika]

Not an idiom - an incomplete sentence.

"The trouble is that I don't like apples"; "The trouble is that they have gone away for a while".

= the annoying thing is that ...

.
If you have heard "The trouble is that" as a complete sentence, the word 'that' refers back to some trouble that has been previously mentioned and the word 'trouble' probably means some kind of 'problem' or 'difficulty'.
.
If you have heard "The trouble is that" as a phrase in a longer sentence, then the word 'that' again refers to the word 'trouble' and what comes after the word 'that' in the sentence will define what the trouble is.
.
That's the best I can do. I don't know anything else that your phrase might mean.
