The continent of Aman had great oceans on both sides, Ekkaia to the west and Belegaer to the east. When the Valar chose this land for their dwelling they needed a defense against Melkor and thus upon Aman's eastern coast they raised the Pelóri, the highest mountains on earth, of which Taniquetil was the tallest of all. Upon this peak were the thrones of Manwë and Varda.
Through the Pelóri was opened a pass, the Calacirya, which brought light to the narrow coastland of Eldamar and the island of Tol Eressëa. Also beyond the mountain wall were two more regions of Aman: Araman to the northeast and Avathar to the southeast. Ungoliant, a great spider of unknown origin, had managed to escape notice in Avathar.
In the north Aman was separated from Middle-earth by the narrow straits of the Helcaraxe. These ice-filled straits served as a path for Melkor and later the host of Fingolfin to return to Middle-earth.
 Flora and fauna
The etymology of the name Aman changed over time in Tolkien's writings. In early linguistic writings, Aman was intended to be a "native Quenya form", derived from the root MAN ("good"). However, in later writings (such as Quendi and Eldar), the name is said to derive from a Valarin word.
 Other names
Aman was also called the Ancient West, Blessed Realm and the Undying Lands or just Valinor. In Adûnaic it was called Amatthāni. In The Hobbit Tolkien also calls this continent "Faerie in the West".
Robert Foster said in his foreword to The Complete Guide to Middle-earth that he did not provide death dates for protagonists who sailed in the West "for they still live". Steuard Jensen, while noting that Tolkien "seems to have been initially unsure" if the "mortals who sailed to the West would remain mortal", comments that are strong arguments in favour of the opposite view, citing from two letters by Tolkien:
...certain 'mortals', who have played some great part in Elvish affairs, may pass with the Elves to Elvenhome...I have said nothing about it in this book [The Lord of the Rings], but the mythical idea underlying is that for mortals, since their 'kind' cannot be changed for ever, this is strictly only a temporary reward: a healing and redress of suffering. They cannot abide for ever, and though they cannot return to mortal earth, they can and will 'die' - of free will, and leave the world.
Frodo was sent or allowed to pass over Sea to heal him - if that could be done, before he died. He would have eventually to 'pass away': no mortal could, or can, abide for ever on earth, or within Time.
Other important arguments against the immortality of the mortals who sailed to Aman can be found in another letter and in a passage from The Akallabêth:
As for Frodo or other mortals, they could only dwell in Aman for a limited time - whether brief or long. The Valar had neither the power nor the right to confer 'immortality' upon them. Their sojourn was a 'purgatory', but one of peace and healing and they would eventually pass away (die at their own desire and of free will) to destinations of which the Elves knew nothing."
The Eldar reported these words to the Valar, and Manwë was grieved, seeing a cloud gather on the noontide of Númenor. And he sent messengers to the Dúnedain, who spoke earnestly to the King, and to all who would listen, concerning the fate and fashion of the world.
‘The Doom of the World,’ they said, ‘One alone can change who made it. And were you so to voyage that escaping all deceits and snares you came indeed to Aman, the Blessed Realm, little would it profit you. For it is not the land of Manwë that makes its people deathless, but the Deathless that dwell therein have hallowed the land; and there you would but wither and grow weary the sooner, as moths in a light too strong and steadfast.’

The Undying Lands were likely thus called like that because immortals dwelled in them, not because they granted immortality.
