What does superaddition mean?
Superaddition means the act of adding something extra to an amount, object, or total that already exists. The word can refer either to the process itself or to the additional quantity produced by it. Unlike the general term addition, superaddition highlights the fact that one contribution has been placed on top of, or included with, something already present. It may therefore describe the mathematical combination of separate quantities, but it can also apply to an added layer of material, text, interpretation, or detail. The word is relatively uncommon in ordinary conversation and sounds formal or technical, especially in mathematical, logical, scientific, or editorial contexts. In general use, it conveys the idea of accumulation: an original element remains, and something further is added. Superaddition is related etymologically to addition and additional, while its prefix super- distinguishes this more specific sense of adding beyond or upon what has already been supplied.
nounThe act or result of adding an extra amount to something already present; an additional quantity added on top of an existing quantity.
- The act or process of adding an extra amount to something already present.
- An additional quantity added to an existing quantity.
"The manuscript shows the superaddition of a later commentary to the original text."
"The formula represents the superaddition of the two contributions to produce the final total."
"Repeated readings of the manuscript suggested the superaddition of several annotations over time."
The plural is used when referring to separate acts or instances of adding an extra amount or quantity.
"The accounts recorded several superadditions to the original estimate."
Superaddition is addition with an encore: something is added to the original amount and to the total that has already accumulated.

Etymology of superaddition
The word combines the Latin prefix super-, meaning over, upon, or beyond, with addition, from Latin additio, an act of adding. Both elements ultimately connect with Latin addere, meaning to put to or add. The prefix gives the word its emphasis on an extra quantity placed upon or included with something already present.
How superaddition is actually used
A rare, formal, and chiefly technical term. It is used when the addition of an amount, layer, or contribution to something already present needs to be emphasized.
Easily confused with superaddition
