I have used "out of conviction" in my sentences. Would you please correct my grammar and punctuation?
1. The well-known writer refused the Nobel Prize out of conviction.
2. Diana never voted nor did she support a political party out of conviction.
3. Out of conviction, the old widow decided to give all her money to charity.
You have a good handle on how to use the phrase. The only thing I'd do is put commas around the "nor . . . party" clause in the middle of 2. That will make it less confusing.
I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.
