Here's the final clues, folks:

#18...take Fiberbabe's French offering, add a word that is in the anagram already.

#9...see answer to #27, add extra name.

#19...anachronistic use of extra syllable on common word.

#12...see an answer already given and add a definite article, dammit! Can I make it any plainer than that!?

Ready?....go!!!...
