Unattached → It is formed from "un-" (meaning not) and "attached" (from Old French *atachier*, meaning to fasten or join). The word "unattached" means not fastened or not joined to something.
Think of 'not' ('un-') being added to 'fastened' — that's why unattached means something that is not fastened or joined.
