Why take a body? Why make a Ring?

[Lalwendë]

Raynor, sorry I wasn't very clear in how I put my last post! It's clear that the Ainur took on forms in order to enter Arda, so this can be the only reason why it was initially done, but as to lmp's original question about 'what was so great about having a body/hroa', I think that being able to use language was a major motivator. Somehow this also ties in nicely with the hidden words (in Tengwar) that were engraved or etched into the One Ring.

Does the use of language also give more opportunities for sub-creation in terms of creating stories, verse and song? This may also explain why those like Melkor were so keen to become wordsmiths. Hmmm, we know that Saruman and Melkor in particular were noted for their skills with language (as was Aule, the Smith, also a wordsmith), was Sauron also so noted?
