Just want to add to Colleen's post.
"Kyo" in the context of the techniques does mean "principle" or "teaching". "Ni" means "second".
Most dojo teach ikkyo, nikyo, sankyo, yonkyo and gokyo. A few teach rokyo and nanakyo. Even fewer teach more still.
In our dojo, the technique names have a definite taxonomy like (this isn't all of it, but I don't want it to be too confusing):
[suwariwaza | hanmi handachi] + [ushiro] + <attack name> + <technique name> + <omote | ura> + <kihonwaza | ki-no-nagare > .
 are optional things, the | means 'or' and the <> means mandatory.
The absence of 'suwariwaza' or 'hanmi handachi' means that it's to be done standing (tachiwaza).
1. Hanmi handachi ushiro ryotedori ikkyo omote ki-no-nagare.
2. Shomenuchi ikkyo ura kihonwaza.
