Confused about

I understand the meaning of bookshelf (as opposed to stand mount or floorstander/tower) Can somebody throw some light on what a "monitor" is ? I have seen some large bookshelves like the "Magico Mini 2" sometimes referred to as mini monitor. As far as dimensions and weight of most bookshelves go.. i would be never call such speakers "mini" in anyway.
Monitor is an abbreviation of studio monitor. Monitors were initially designed for recording studios and are meant to be listened in the nearfield and used small rooms. Monitors have a reputation of being very revealing and detailed speakers. Bookshelf and/or stand mounts are designed to be more versatile in their placement and sound. Today, monitors and bookshelfs have become marketing terms in many instances.
