Not joined or linked together; lacking a connection or relationship.
The ideas in his essay were unconnected, making it hard to follow his argument.
Unconnected → It is formed from "un-" (meaning not) and "connected" (from Latin "connectere", meaning to join together). The word "unconnected" means not joined together or lacking a connection.
Think of 'not' ('un-') being added to 'joined together' ('connectere') — that's why unconnected means something that is not joined.
