Third-person singular form meaning to earn as total revenue before deducting expenses, or to amount to in total.
From Old French 'gros' (large, whole), used as a verb to describe totaling up full amounts without subtraction, popular in accounting and theater terminology.
When a movie 'grosses' $100 million, that's the whole pile of money earned before anyone gets paid—it's much larger than the actual profit the studio keeps!
