To add, we consider it subconscious when we do thing involuntarily such as answering a question without thinking about it or doing an action by habit instead of thinking about doing it. When we develop habits and move involuntarily because of it we say that we did that action subconsciously. For example, I crack my neck a lot to release the tension but sometimes my friends don't like it because it sounds gross to them. I will accidentally do it without thinking and so when they get mad at me I'll tell them I did it subconsciously. Hope this helped.

I would also add that unconscious can mean somebody is completely knocked out. Ex: If a boxer gets punched in the head, he might become unconscious.

awww I got it. Thank you very much everyone!!

Really good question ^_^ If you want to get very technical, we would make 2 categories: conscious vs unconscious. -conscious is awake, aware of your surroundings, alert, responsive, mindful, etc. -unconscious is strictly not conscious, inert, etc. Most of the time, these are words are used as adjectives. We say things like, "He's unconscious." However, in speech, when we use the word subconscious, we usually use it as a noun and refer to it as an existing part of the mind (we usually say "the subconscious") With this information, to answer your question: subconscious would fall right between conscious and unconscious. Its a psychological term that means you're in the mind but you're not aware of it, and not immediately available to respond. Which would not be the same thing as unconscious because unconscious is absolute.

I would add that unconscious is commonly used as an adjective. For example, "When he fell and hit his head, it knocked him unconscious."
