The Marvelous Miss M.'s Meme

I've been meme-tagged from down under. Here are the instructions:

Your task, should you choose to accept it, is to tell us what these words mean to you.

Here are the words, and I'm going to give you a link with each one--a link that explains what those words mean to me.

• ethereal
  
• jubilate.
• cossie.
• feign.

And that was fun! Miss Melly tagged oldest son, too, and his answers are here.
