What does excess mean?
Excess refers to an amount of something that goes beyond what is needed, allowed, or normal — whether it be extra material trimmed from a recipe, weight above a permitted limit, or money spent past a budget. The word carries both a neutral, quantitative sense and a strongly negative moral one: speaking of a person's 'excesses' implies indulgence and lack of restraint, evoking centuries of warnings against overindulgence in food, drink, or luxury. It also serves as an attributive adjective, as in 'excess baggage' or 'excess calories', and in British insurance terminology denotes the fixed portion of a claim a policyholder must cover themselves. Derived from the Latin verb 'excēdere', meaning to go out or beyond, excess shares deep roots with words like 'exceed' and 'proceed'. Its enduring usefulness lies in naming not just surplus, but the human tendency to cross limits.
An amount of something more than is necessary, permitted, or usual.
"Rinse the rice to remove any excess starch."
Often used with 'in excess of' as a formal way of stating quantities beyond a figure.
Immoderate indulgence in activities, especially eating, drinking, or spending.
"The novel chronicles a rock star's descent into excess."
Amounting to more than what is necessary, permitted, or usual; additional and unwanted.
"Passengers were charged a fee for excess luggage."
Used almost exclusively as an attributive adjective before a noun.
The plural usually denotes repeated acts of immoderate behavior rather than multiple quantities of surplus.
"The memoir recounts the excesses of his youth."
Excess comes straight from the Latin for 'a going out beyond' — the same ancient root that gave us 'succeed', which literally means to 'go under and onward' toward a goal.

Etymology of excess
Excess derives from the Latin 'excessus', meaning 'a going out or beyond', formed from the verb 'excēdere' ('to go forth, go beyond'), itself composed of 'ex-' ('out') and 'cēdere' ('to go'). The word entered English via Old French in the medieval period, initially carrying senses of departure and transgression before settling into its modern meanings of surplus and overindulgence. The root 'cēdere' also produced 'exceed', 'proceed', 'succeed', and 'concede'.
