Here's why:
* "Loaf" is a noun referring to a shaped bread. There's no commonly used rhyming word that also means bread.
* "Cotton" is a noun referring to a soft, fluffy fiber. While there are rhyming words like "gotten" or "foughten," they don't carry the same meaning.
If you're open to close rhymes, you could consider:
* "Loaf" could be rhymed with "scope" (meaning range or opportunity), but it doesn't directly relate to bread.
* "Cotton" could be rhymed with "gotten" (meaning obtained or acquired), but it doesn't specifically refer to the fiber.
