"I have an answer for your question, but you might not like it."

What would be a single English word that could reflect the phrase (if such a word exists):

I have an answer for your question, but you might not like it.

or

We corresponded, but you might not like the outcome.

The word shouldn't be an exact equivalent, but must reflect the situation as closely as possible.

Solution 1:

It really depends on the context of the response or outcome.

However, if I was starting correspondence addressing a question and I knew that they wouldn't be too pleased with the answer, I would probably start with "Unfortunately".

It probably doesn't correlate directly with what you say but I can think of enough scenarios to warrant me suggesting it.

Dear Sir, I bought this tent and it leaks. I would like a refund.

Dear Customer. Unfortunately we can't offer refunds after 28 days.

or

Can I bring my dog to the hotel?

Unfortunately our policy does not allow pets in the room

Solution 2:

This question reminds me of some I've got some good news, and some bad news jokes.

As for getting it all into one word, you might consider jeremiad, as in:

I have a jeremiad for you.

According to Macmillan:

jeremiad: a long sad complaint or list of things that have gone wrong

It's neither a well-known nor common term, and perhaps it's not an exact fit, either. Then again, as RegDwight said in his comment, it's an awful lot of meaning to pack into one word, and that's the best I could muster.

Solution 3:

You've requested a "word that could reflect the phrase (if such a word exists): 'I have an answer for your question, but you might not like it'". If this is not a trick question, mirror is the word you want. Or if you mean, reflect the sense of the phrase, then let-down (a noun, idiomatic for "A disappointment or anticlimax") is suitable.
