Jlinger handled this one well, but I will make a couple of additional comments.
His mother felt like she was saying goodbye to him for the last time.(You can't come up with one phrase that fits all situations.)
I wanted the moment to last always.That is, I think, a poetic rendering of the more usual statement.
Perhaps you could critique the rest of them?
Thank you very much for your post. You said "Try replacing "forever" with "for once and for all" in your sentences. If it works, then you can use "for good."
Do you mean 'for good' mean exactly the same as 'for once and for all'?
Thank you very much for answering most of my questions. After your explanaton, I'm afraid I still need some help.
1)"This time she's leaving for good."
Can I use 'forever' instead of 'for good' here? Could you tell me why if not?
2)"I'm moving to Europe forever."
I'm confused why 'forever' doesn't work here? Could you tell me the meaning of the sentence?
3)"When her son went to fight in the war, his mother felt she'd say goodbye to him for good."
I'm coufused why 'for good' is wrong here. Doesn't it mean saying goodbye once and it is over?
4)"I wanted that moment to always last."
Doen't 'always' mean 'forever' in the case? Could you tell me its meaning here?
5)"I wanted that moment to last for good."
Does 'for good' fit here?
6)"Remember that "for good" has two possible meanings"
Could you tell me what the possible meanings you refered to are?
7)"If you think it is a good thing that the artworks were lost then say that they were lost for good."
Do you mean if it's a bad thing, don't use 'for good' in "Many valuable works of art were lost forever"?
But you said 'The phrase "for good" (somewhat ironically) is usually used in the negative sense (when it is not being used in the sense of "for good purposes"), why can't 'for good' be used here?
8)"After her death, their lives changed forever."
I think 'for good' is fine here.
Could you tell me if I'm right or wrong?
9)"I like the house but I don't imagine I'll live there forever."
I think 'always' is fine and 'for good' isn't here? Is it true?
10)"Nobody lives forever."
Is 'always' fine here?
Is it correct that 'for good' doesn't work here?
11)'We thought she'd come over for a visit, but it seems she's staying for good.'
Does 'for good' sound ironic and mean a bad thing in the case?
Can I use 'forever' or 'always' instead of 'for good' here?
Thank you very much.
Do you mean If I use 'forever' in 'She is leaving forever', it means she is leaving indefinitely; she is leaving with the intention of keeping it going for all time in the future?
Can 'forever' mean 'once and for all' sometimes or it doesn't mean that at all?
Thank you very much for your reply.
