Inter-locked means to be connected or intertwined with another object or system. The opposite of this would be words like disengaged, unconnected, disentangled, or detached. These words suggest a sense of separation, where things are not connected, intertwined, or linked in any way. For example, disentangled branches of a tree would mean they are not wrapped or entwined with each other. Similarly, unconnected electrical wires mean they are not linked or joined in any way. These antonyms for inter-locked signify a sense of freedom, independence, or detachment from something else.
