IPA: /ɪmˈpjuːtə/
KK: /ɪmˈpjuːtər/
A person or thing that attributes or assigns something, often blame or responsibility, to someone or something else.
The imputer of the error was quickly identified during the investigation.
Imputer is formed from "in-" (meaning into) and "putare" (meaning to reckon or consider). The word refers to someone who attributes or assigns something, often blame or responsibility, to another.
Think of someone 'putting' ('putare') something 'into' ('in-') the account of another — that's why an imputer is someone who attributes responsibility.
