If something is foredoomed, it is already marked — by fate, or by the way things are set up — to fail or to be unhappy. The ending feels decided before the story even starts. It is a literary, rather heavy word; you will meet it in books, film talk, and newspaper comment (the plan was foredoomed), not when someone is ordering lunch. People often say foredoomed to failure or foredoomed to disappointment. It is stronger than “unlikely to work”: it says the bad end was waiting. Though actually, speakers use it for a feeling about the future, not because they have proof from the gods. There is a plainer cousin, doomed. Foredoomed just leans on the “already, beforehand” part.

注定失敗的、命中注定不幸的（書面、文學用語；口語多半只說 doomed 或「注定沒好下場」）
