KK: /ɪnˈtɜr.pə.leɪ.tər/
A person or tool that adds or inserts something into a text or data set, often to fill in gaps or create a smoother transition between points.
The interpolator helped to create a more accurate representation of the data by filling in missing values.
Interpolator → It is formed from "inter-" (meaning between) and "polare" (from Latin, meaning to make smooth or to adjust). The word "interpolator" refers to a function or process that makes adjustments or estimates values between known data points.
Think of something that 'makes smooth' ('polare') between two points ('inter-') — that's why an interpolator estimates values in between known data.
