IPA: /ˈbaɪˌprɒdʌkt/
KK: /ˈbaɪˌprɒdʌkt/
A secondary result or effect that happens as a result of making something else.
The factory's waste is a byproduct of the manufacturing process.
Byproduct → It is formed from "by" (meaning secondary or alongside) and "product" (from Latin "productus", meaning something produced). The word "byproduct" refers to something that is produced as a secondary result alongside the main product.
Think of something that is produced "alongside" the main item — that's why a byproduct is a secondary result.
