Hilchot Shabbat - פרק י״ד

<p><strong>Perek י״ד: The Four Domains Defined</strong><br>This Perek lays out precisely what separates the four categories of space for the laws of carrying: Reshut HaYachid (a true private domain), Reshut HaRabim (the public domain), &quot;Karmelit&quot; (an intermediate space that is neither), and Makom Patur (an exempt area too small to count). Through a long series of real-world cases, walls, pits, boats, hills, and posts, the Rambam works out exactly where each boundary falls, and the resulting rules for what can and can&#39;t be thrown, passed, or carried between them.</p>
