The term "blocked-out" suggests an obstruction or hindrance. Its antonyms would be words that refer to the opposite, such as unrestricted, unfettered, clear, or unobstructed. These antonyms imply the presence of openness, smoothness, and ease of access. To be unrestricted means that there are no limitations or constraints, while unfettered refers to the absence of shackles or restraints. Both clear and unobstructed denote transparent or obstacle-free pathways. Thus, while "blocked-out" pertains to closures, blockages, or hindrances, its antonyms suggest that there is free movement or access in a particular direction.
