What does halving mean?
Halving means reducing something by 50 percent or dividing it into two equal parts. It is used as a noun for the process or result of making such a reduction, and as a verb for the act of reducing or dividing something in that way. The word appears frequently in discussions of prices, costs, sizes, distances, processing times, and other measurements, where it clearly emphasizes a proportional change. For example, a company may announce that it is halving delivery times, while a design change may result in halving the amount of material used. Although “halving” can describe division into two equal parts, its most frequent contemporary use is for reduction to half the original amount. It is a precise and economical alternative to longer expressions such as “reducing by 50 percent” and “cutting in half.”
The process or result of reducing something to half its previous size, amount, value, or duration; also, the act of dividing something into two equal parts.

Where does halving come from?
The word is the gerund of “halve,” formed by adding the suffix “-ing.” “Halve” comes through Middle English from Old English “half,” the English member of a Germanic word family that also includes German “halb” and Dutch “halve.” “Behalf” preserves the same “half” element in a separate compound formation.
