IPA: /ˌspɛsɪfɪˈkeɪʃən/
KK: /spɛsɪfɪˈkeɪʃən/
A detailed description that outlines the requirements or standards for something, often used in construction or manufacturing.
The architect provided a clear specification for the new building project.
Specification → It is formed from "speci-" (from Latin "specere", meaning to look or see) and "-fication" (from Latin "facere", meaning to make or do). The word refers to the act of making something clear or detailed by looking at its specific aspects.
Think of 'looking' ('speci-') at the details and 'making' ('-fication') them clear — that's what specification means.
