Where does halve come from?
The modern verb developed in Middle English from the Old English noun “half,” which belonged to the Germanic language family. Its original sense was to divide something into two equal parts or take one of two equal portions; the modern sense of reducing an amount by one-half follows naturally from that usage. Related forms appear in other Germanic languages, including German “halb” and Dutch “halve.”
