I am jubilant

I'll be jiggered. I couldn't think of any adjectives that start with J when I needed them. Jazzy, jumpy, joyful, jerky, junky, jade.

I have it, the penultimate J-word: Jubilant!

Juvenile adjectives

I was trying unsuccessfully to think of adjectives that start with the letter J.

Now I can name some:
Jade, jazzy, jumpy, junky, jerky, jilted, jiggling, or would it be jiggly?  and juvenile.

Do words that start with G, but sound like J count?
Germy, ginfilled, German, germaine, generous...
