What does feloniously mean?
"Feloniously" is a formal adverb meaning in a way that constitutes a felony — that is, a grave crime punishable by imprisonment for more than a year. It belongs to the specialized vocabulary of the courtroom: prosecutors use it to characterize conduct such as theft, assault, or homicide when the circumstances meet the legal threshold for felony liability. The word rarely strays into ordinary conversation, though it may appear figuratively in journalism or humor to suggest something done with outrageous criminal flair. Its tone is dry and technical rather than emotive, carrying no judgment beyond the legal one. Derived from "felony," which traces back through Old French "felonie" to Medieval Latin "felonia," it is part of a small family of terms — felon, felonious, felony — that English has used since the medieval period to draw the line between minor offenses and serious crime. Knowing the word helps readers navigate indictments, statutes, and news coverage of criminal cases.
adverbIn a manner that constitutes a felony; with deliberate criminal intent as defined by law. It is used almost exclusively in legal language to describe an act committed under circumstances that make it a serious crime.
- In a manner amounting to a felony; with criminal intent sufficient to constitute a felony.
"The indictment charged that the defendant did feloniously steal merchandise valued at over ten thousand dollars."
"The court found that the accused had feloniously taken the vehicle from its rightful owner."
"The statute punishes anyone who knowingly and feloniously transmits stolen funds across state lines."
The word 'feloniously' appears thousands of times in American indictments — often in the archaic formula 'did feloniously' — making it one of the most quoted words most people never use in conversation.

Etymology of feloniously
"Feloniously" derives from "felonious" (itself first recorded around the early 17th century), plus the adverbial suffix -ly. The root "felony" came into Middle English via Old French "felonie" from Medieval Latin "felonia," a term of uncertain ultimate origin used in feudal and criminal law to denote treachery or grave offense. Cognate forms such as "felon" and "felonious" share this same legal lineage.
How feloniously is actually used
"Feloniously" is a formal legal term confined almost entirely to statutes, indictments, and court proceedings; it would sound stilted or jocular in everyday speech. In common-law jurisdictions it traditionally appears in set phrases such as "did feloniously steal" or "feloniously and maliciously." An act described as felonious is more serious than a misdemeanor.
