I don't know about the other languages but in German there is a term that describes another option. As page brakes you can define rows or columns. It is perplexing to use the term of line brake or word wrap. Line brake means word wrap which is in Calc within a single cell. But not the pagination of a sheet. So for page brakes it would be easier to separate the terms if it would be called something like page brake before row or page brake before line.
@Sophie, @Eike, @Miguel, any opinion here?
Well, line break is not used for sheet page from what I know. I found pretty clear what page break and line break mean, the option is under Sheet in Calc and Insert in Writer, so easy enough to find and use. Maybe I don't understand, or the translation in German may use another term, but I won't be for changing the English string at the moment. Sophie
