Ela ficou realmente tentada .
Isso é algo que Tolkien descreve na Carta 246:
In the 'Mirror of Galadriel', it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond. But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power. But this the Great had well considered and had rejected, as is seen in Elrond's words at the Council. Galadriel's rejection of the temptation was founded upon previous thought and resolve.
Também é explicitamente mencionado na Carta 210:
The disappearance of the temptation of Galadriel is significant.
E uma nota de rodapé na carta 297:
Her prayer was granted – but also her personal ban was lifted, in reward for her services against Sauron, and above all for her rejection of the temptation to take the Ring when offered to her. So at the end we see her taking ship.
E a carta 320:
At the end of the First Age she proudly refused forgiveness or permission to return. She was pardoned because of her resistance to the final and overwhelming temptation to take the Ring for herself.
Existem, sem dúvida, outros exemplos em outros lugares, mas estes devem ser suficientes para mostrar que a intenção do autor é que ela foi tentada.
