Theft Words
‘Theft‘, ‘larceny‘ and ‘steal‘ all refer generically to wrongfully taking someone else’s property. The differences between those words are very subtle. I would say that ‘theft’ suggests that the actor steals regularly as a thief, while ’steal’ suggests that stealth may have been involved, and ‘larceny’ is most common in statutes and legal proceedings.
‘Burglary’ and ‘robbery’ are much more specific: A burglary is entering a building, especially a home, with intent to steal, while a robbery is theft by the use or threat of violence.
Finally, ‘embezzlement‘ and the more obscure ‘defalcation‘ are both thefts by someone entrusted with the stolen property.
