grand larceny noun

the crime of theft of another's property (including money) over a certain value (for example, $500), as distinguished from petty (or petit) larceny in which the value is below the grand larceny limit. Some states only recognize the crime of larceny, but draw the line between a felony (punishable by state prison time) and a misdemeanor (local jail and/or fine) based on the amount of the loot.
