What does nailed mean?
Nailed is the past tense and past participle of the verb nail, meaning to fasten something by hammering a nail into it. In everyday informal English, it also means to accomplish a task very successfully, understand a concept quickly, or describe something precisely. For example, someone who gives an excellent presentation may be said to have “nailed it,” while a student who understands a difficult lesson may say they “nailed the explanation.” These extended meanings are especially associated with American usage, although they are widely understood in British English as well. The word is often used in phrases such as “nailed it,” “nailed the answer,” and “nailed down,” where it conveys immediacy and success rather than literal physical fastening.
To fasten something by driving a nail into it; to secure or fix something in place.
"The carpenter nailed the boards together."
The literal meaning is formal and neutral. The past participle can follow passive constructions such as “the door was nailed shut.”
Informally, completed with great success or accuracy; clearly understood.
"That was a nailed performance."
This use is informal and is especially common in American English.
From securing a plank with a hammer to mastering a difficult problem, “nailed” has become a vivid shorthand for getting something exactly right.

Where does nailed come from?
Nailed is formed from the Old English næl, meaning a pointed metal object used for fastening, by adding the inflectional ending -ed. The related verb nail developed in Middle English and ultimately also derives from Old English næl. The word’s modern figurative senses, especially “achieved successfully” and “understood clearly,” developed later from the idea of securing something firmly in place.
