Expert writing Tips
Best practice
In professional settings, this phrase acts as a neutral way to admit a lack of expertise without sounding overly apologetic, as seen in many Ludwig examples from media interviews.
Common error
Writers sometimes mistakenly use "I don't know nothing about it" in an attempt to be emphatic. This is a double negative that, in standard English, technically means you do know something, or simply marks the writing as non-standard. Stick to "I know nothing about it" or "<a href="/s/i+don't+know+anything+about+it" target="_blank" rel="alternative">i don't know anything about it" for clarity.

Linguistic Context
The phrase "I know nothing about it" serves as a negative declarative statement. Grammatically, it consists of a subject ("I"), a transitive verb ("know"), and a negative pronoun ("nothing") acting as the direct object, followed by a prepositional phrase ("about it") that provides the scope of the ignorance. Ludwig highlights its utility in various sentence structures where the speaker aims to establish a boundary of knowledge.
