Parv is incorrectly written, and should be written as "parvon" as meaning:
Parvon is an alistana word derived from parva. Was the longitudinal grouping of the trite harvest ( straw and grain ) about 5 or 6 meters and in a direction perpendicular to the presumed direction of the wind, that in ready always was Portuguese, i.e., Castilian, i.e., East, or West to throw or clean the grain. Currently already not be threshing.
