Partially aware of your surroundings or sensations, but not fully conscious.
After the accident, he was semiconscious and could barely respond to questions.
Semiconscious → It is formed from "semi-" (meaning half) and "conscious" (from Latin "conscire", meaning to be aware). The word "semiconscious" describes a state of being only partially aware or awake.
Think of being 'half' awake ('semi-') and 'aware' ('conscious') — that's what semiconscious means.
