Re: "in fear for his future and his life" (the actual quote, emphasis mine)
With a fair amount of certainty, before today, I would've stated that "in fear for his future" is not idiomatic (in AmE) and that in fear for one's life is an idiom, with some variation, but you can't add another noun phrase to it, not in that way.
But in deference to the author (multilingual American, senior writer/editor, magna cum laude, etc.), I'm not so sure now. Maybe it was a transcription error. I don't know, but it's an odd combination (future and life). I thought I could find plenty of better ones online.
But all I found (including in) were these common, slight variations:
- in fear for one's life (US); in fear of one's life
afraid of being killed
She claimed that she shot the burglar because she was in fear for her life. [M-W]
- in fear for one's/someone's life
feeling that one/someone is in danger of dying or being killed [M-W]
In fear for the boy's life, his dog dragged him out of the shallow water by his life jacket.
- in fear for one's/someone's safety
In fear for her safety, the victim complied with the suspects’ demands and directed them to valuables. [LA Times]
Stalking laws criminalize a pattern of conduct in which an offender follows, harasses, or threatens another person, putting them in fear for their safety. [FindLaw]
- go in fear of (one's) life
To constantly fear that one may be in serious danger of being killed.
Ever since I received that threatening phone call, I've gone in fear of my life. [TFD]
This 4th one is unfamiliar to me. I'd probably say 'feared for my life' instead.
That's all I have, after all those searches. I thought I would find a dozen variations, but I didn't. I still can't think of another NP that I would add to it. Maybe you could though. The title and the question are one and the same:
Is "in fear for one's life" an idiom with limited variations or can you add another noun phrase to it?
