ETYMOLOGY
from Latin edaci- (nominative edax), from edere (to eat) + -ous
EXAMPLE (for n. 1.)
“… Nor is this the sole circumstance that should, in mere justice, be
considered in connection with the rise of Christian monachism; for
before the mere facts can be understood, and certainly before the due
measure of blame can be assigned to the parties concerned, it is
indispensable that we divest ourselves of the prejudices, physical,
moral, and intellectual, which belong to our austere climate, high-toned
irritability, edacious appetites, and pampered constitutions; to our
rigid style of thinking, and to our commercial habits of feeling. …”
