Also means
faded, dim (of light or color)
Usage Note
Scemo is the everyday colloquial word for 'stupid' or 'dimwit' and is milder than idiota or cretino. It also functions as a noun: uno scemo (a fool). The original sense — still alive in formal and literary Italian — is 'diminished, faded' (e.g., luna scema, the waning moon). Do not confuse with schiuma (foam) or schema (diagram).
Examples
"Non fare lo scemo, hai capito benissimo."
Natural Translation
