IPA: //ˈsʌb.skeɪl//
KK: /sʌbˈskeɪl/
A smaller part of a larger scale used for measuring or evaluating something.
The survey included several subscales to assess different aspects of customer satisfaction.
Subscale → It is formed from "sub-" (meaning under or below) and "scale" (from Latin "scala", meaning ladder or steps). The word "subscale" refers to a smaller scale or a scale that is below a larger one.
Think of something that is 'under' ('sub-') a 'ladder' or 'steps' ('scala') — that's why subscale means a smaller version of a larger scale.
