Phoenix, you should think about more options.

You said that he combined only two words, *Sad*+*Horrible*, but there are more options! He could combined *Sad*+*Horri*ble+Terri*ble*!

There isn't any evidence that my or your assumption is correct, so we will have to wait until he speaks.

You only combined two words! Therefore, you didn't have 3 words in one!
