Unless someone died in the midst of spelling acrostic, or has some kind of speech defect that prohibits the proper pronunciation of across, this isn't a word.
If someone should happen to find some incredibly archaic definition for it, well, great. Until then... ARGH!
These citations may well be authentic, but this word in common usage is still bad English. I second the ARGH.
Thanks danpage0! Glad to know it's actually a word after all.
Used by Alfred Lord Tennyson in Crossing the Bar, Leonardo di Vinci used it also. It has been around for quite a while.
