In the tenth (1990) and following Urantia Foundation Printings, "untrammelled" was replaced with "untrammeled." Both are acceptable spellings, so it is unclear why such a change would have been made.

Original Paragraph:

^{P1201:3, 109:7.2} Personalized Thought Adjusters are the untrammelled, unassigned, and sovereign stabilizers and compensators of the far-flung universe of universes. They combine the Creator and creature experience -- existential and experiential. They are conjoint time and eternity beings. They associate the prepersonal and the personal in universe administration.
