Plural of Wits
In expressions such as “keep your wits about you” or “live by your wits,” “wits” is grammatically plural and lexicalized in that form. The singular noun “wit” exists, but its senses do not make it a mechanical one-item singular of every plural “wits” expression.
“Wits” is already a plural noun/expression when it means practical intelligence or the ability to think quickly. Singular “wit” has related meanings but is not simply one unit of “wits.”
Key details

|---|---|---|
| practical intelligence expression | wits | Keep the plural form. |
