To the best of my knowledge, LO never breaks lines within words, only at word boundaries. However, it sometimes makes sense to break a line within a longer word, to reduce raggedness / excessive empty space on that words line or other lines in the paragraph. This capability would go well with paragraph-level line breaking logic, see bug 154355.
Hyphenation? https://help.libreoffice.org/7.5/en-US/text/swriter/guide/using_hyphen.html
Created attachment 186177 [details] Paragraph with hyphenation on but no hyphenation Example
(In reply to Mike Kaganski from comment #1) > Hyphenation? > https://help.libreoffice.org/7.5/en-US/text/swriter/guide/using_hyphen.html Oh. Well, that _sounds_ like what I'm asking. But - when I turn on automatic hyphenation, it doesn't seem to do anything. i.e. even very long words don't get hyphenated to fit more text onto a line
This is a question of missing hyphenation package for a given locale (en-IL in case of attachment 186177 [details]).
(In reply to Mike Kaganski from comment #4) > This is a question of missing hyphenation package for a given locale (en-IL > in case of attachment 186177 [details]). Do we have a hyphenation fallback mechanism from LANG-LOCALE to LANG general or LANG-OTHERLOCALE?
(In reply to Eyal Rozenberg from comment #5) No AFAICT; but indeed, it could be added - lately, I did a similar work on spell checkers, so when generic checkers exist, the fallback would find it. Yet, fallback to lang-OTHERLOCALE would need some hardcoded rules...
Created attachment 186212 [details] Alternate sample slide (PPTX) Slide 21 of attachment #127409 [details] from bug #102261 ran into the same issue, and this is a reduced reproducer. Once I manually set "Tools - Language - Hyphenation" the table cell shrank from 3 lines to 2, as in PowerPoint. This is really not ideal from a user perspective where one usually simply wants to view and *existing* presentation and have it appear similar to how it shows in PowerPoint. Is there anything we can do (by default)?

So, that sounds like a different issue, which is non-enabling of hyphenation when importing a PPTX. Please consider opening a separate bug for that.
I was actually wondering, too; filed separately as bug #154399 now.
