portion

The word centers on the act of dividing a whole into manageable or designated pieces. It carries a stronger sense of "allocation" than the generic word "part." In a culinary context, it refers specifically to the quantity assigned to one individual, often carrying connotations of fairness, generosity, or restriction (e.g., "portion control"). When used in financial or legal contexts, it suggests a formal distribution of assets, where each "portion" is a rightful share based on an agreement or law. As a verb, it describes the mechanical or administrative process of splitting something up, though this usage is less common than the noun form.
