Description
No Lonely Words solves a common Polish typography problem: single-letter conjunctions and prepositions (a, i, w, z, o, u…) left alone at the end of a line. The plugin replaces the trailing space after these words with a non-breaking space ( ) so they always stay attached to the following word.
How it works
Content is processed once when a post is saved and the result is stored in post meta. On every subsequent frontend request the plugin reads directly from WordPress’s in-memory meta cache (no regex, no extra database queries). For posts created before activation, inline processing runs on the first view and is cached for the rest of that request.
Supported words
Polish conjunctions and prepositions: a, i, w, z, o, u, do, ku, na, od, po, we, za, ze, ale, czy, bo, nie, już, też, się, jak, co, to, oraz, lecz, więc, przez, przed, przy, nad, pod, bez, dla, m.in., np., tj. and more.

FAQ
-
Does it affect the editor?
-
No. The plugin only modifies the output of content filters. The raw post content in the database and in the editor stays unchanged.
-
Does it work with WooCommerce?
-
Yes. Product titles, short descriptions, and full descriptions are all supported via dedicated WooCommerce filters.
-
Does it work with caching plugins?
-
Yes. Processed content is stored in post meta (a standard WordPress database table), so it survives full-page cache flushes and is always correct regardless of caching setup.
-
How do I process existing posts?
-
Go to Posts All Posts (or Products), select all, and use the Bulk Edit Update action. This triggers
save_postfor each post, which processes and stores the content. Alternatively, any post re-saved individually is processed immediately. -
Does it work with WPML or Polylang?
-
The plugin uses standard WordPress filters and post meta, so it is compatible with WPML and Polylang. Each language version of a post is stored and processed independently.
