Relating to or used for plowed land, fields, or agricultural fields; pertaining to arable land.
From Latin arvalis (of fields), derived from arvum (field, plowed land), possibly from an Indo-European root meaning 'to plow' or 'to till.'
The Romans had 'Arval Brethren'—priests dedicated to protecting fields—and they're famous for being one of the oldest religious brotherhoods because farming was that important to civilization.
