    noun
    Intelligence and cleverness, or the practical know-how that gets things done.

    Similarbrains, savvy, know-how, intelligence

    Note

    A casual noun built from the clever adjective, and it lives only in the plural form smarts. The common frame is have the smarts to do something, and a word in front narrows the kind of cleverness: business smarts, street smarts. It is never counted, so a smart or two smarts will not work. In a job reference or a report, intelligence or know-how reads better.
