IPA: /ɪnˈækjərətli/
KK: /ɪnˈækjərətli/
In a way that is not correct or precise; done wrongly or without accuracy.
The report was filled out inaccurately, leading to several mistakes.
Inaccurately → It is formed from "in-" (meaning not) and "accurate" (from Latin "accuratus", meaning careful or exact) and the suffix "-ly" (meaning in a manner). The word "inaccurately" means in a manner that is not careful or exact.
Think of 'not' ('in-') being added to 'careful' ('accurate') to remember that 'inaccurately' means doing something in a way that is not careful or exact.
