adj

1. (obsolete) foul
   Paradise Lost, John Milton Say first, for Heav'n hides nothing from thy view / Nor the deep Tract of Hell, say first what cause / Mov'd our Grand Parents in that happy State / Favour'd of Heav'n so highly, to fall off / From their Creator, and transgress his Will / For one restraint, Lords of the World besides? / Who first seduc'd them to that fowl revolt?
