Most tethered means being tightly controlled or restricted. Its antonyms would be words like free, liberated, unencumbered, or unbound. When something is free, it means it isn't restrained, while liberated means it's released from captivity, suppression, or confinement. Unencumbered suggests that an object or person is not weighted down by any burden or obstacle, while unbound suggests the absence of any limiting factor or barrier. In contrast, being the 'most tethered' implies being held down by different social or personal constraints, so these antonyms are useful in describing scenarios where people or objects break free of these limitations.
