Usage

What does inaccurate mean? Inaccurate describes something that is incorrect, false, or not quite right, as in I came home at 9:30 last night, so saying I was out all night is inaccurate. Inaccurate is the opposite of accurate, which describes something being free of defects or errors. You might describe a scale is inaccurate if it doesn’t show the precise weight of something. Inaccurate can also describe something that is wrong or untrue.
