I think the word for writing is wrong

[EywaBlessMe]

As you (should) know, pamrel is the na'vi word for writing. It comes from 'pam'-sound, and 'rel'-image.
I don't like the rooting.
To me, a 'sound-image' implies a phoneme, the smallest discrete unit of speech.
I believe a better choice is 'lì’urel', or 'word-image'. Doesn't this make better sense? What is writing but word images anyway?
Perhaps a 'sound-image' could be a letter.
Anohter, but not as good, suggestion would be 'tìlawkrel', or 'discourse-image', but this word might be better suited for a book.
Can anybody run this past Doc Frommer or Taronyu?
