So I was thinking about the word "invisible".
There's no way to say that you can't see something without it involving a negative.
You can say "invisible", "unseen", or whatever but no single word on it's own for it.
It's different though for other aspects such as sound or movement. You have "inaudible" but also, "silent". There's "immobile", but also "still".
Where's the single word that means "invisible" without negating some other word??

So yeah anyway... I just gave myself a headache.
