Commentary:

Note this is not the word contradict. This is contra-indicate. As it, do not indicate. Apparently a medical term. There is no way I’ll ever end up using this word just because it looks like contradict and its meaning is very similar to contradict. It just makes me uncomfortable. Yeah, that’s it.
