IPA: /ˈmuːnʃaɪnər/
KK: /ˈmunˌʃaɪnər/
A person who produces or sells illegal alcoholic beverages, especially whiskey made in secret.
The authorities arrested the moonshiner for operating an illegal distillery in the woods.
Moonshiner → The word is formed from "moon" (from Old English *mōna*, meaning the natural satellite of Earth) and "shiner" (from the verb "shine", meaning to emit light). A moonshiner is someone who produces illicit alcohol, often at night, under the light of the moon.
Think of the 'moon' shining down at night, which helps you remember that a moonshiner is someone who makes alcohol under the cover of darkness.
