What word can I use that doesn't set off a wiggly red line on my spellchecker? Having a blank brain moment.
Inscrutable, impenetrable, mysterious, indecipherable, enigmatic, arcane, unknown, and the ever popular ... unable to be understood I don't know the context so... sorry if some of these won't work.
*goes for enigmatic* Thankee *imaginary reputation since I apparently gave you too much already lately*
I guess unknown was the real word I was thinking of, but it only has 2 syllables and didn't fit right.
