definitions & notes only words
  1. conscious
    having awareness of surroundings and sensations and thoughts
    It was hardly a conscious decision, certainly not one I recall agonizing over.Salon (Mar 24, 2013)
    Because the prefix "con-" means "with" in this case, and the root "sci-" means "knowledge," the word "conscious" means, simply "with knowledge," or, "with awareness."
  2. conscience
    a feeling of shame when you do something immoral
    Indeed, individual conscience is a core value in Catholic teaching.
    When your conscience troubles you, it is because you know ("sci-") that you've done wrong. You may be able to deny your wrong-doing to others, keeping them unaware, but you can't fool your own conscience.
  3. conscientious
    characterized by extreme care and great effort
    “Daniel’s one of the most prepared and conscientious pitchers in Major League Baseball.”Washington Post (Nov 11, 2011)
    A conscientious person works with great attention and knowledge of the task at hand. To be conscientious is to attend to details, to be highly aware (knowledgeable) of the task, and to be thorough.
  4. omniscient
    infinitely wise
    "Omni-" means "all" ("omnivore"), so "omniscient" means "all-knowing." This word is often used in a religious context, referring to an all-knowing God. It is also used when talking about stories. A narrator who is telling the story, but not a character in it, is said to be "omniscient," or all-knowing about the feelings and activities of all of the characters. In other stories, the narrator is not all-knowing, but just another character telling the story from his point of view.
  5. subconscious
    just below the level of awareness
    Your innate ability and your subconscious mind will take over.Seattle Times (Jul 5, 2012)
    Because the prefix "sub-" means "under," subconscious thoughts and feelings are those that lie under the conscious level. They exist, but we are unaware of them. Subconscious thoughts and feelings may express themselves in dreams or in vague feelings that we can't explain.
  6. unconscious
    without active awareness
    They are involuntarily managed in the vast processing system of the unconscious mind.Forbes (May 14, 2013)
    When you do something unconsciously, you do it automatically. An unconscious person is "knocked out," either through a deep sleep, anesthesia, a head injury, or a comatose state.
  7. self-conscious
    excessively aware of your appearance or behavior
    At work she felt increasingly self-conscious around male customers.
    If you've ever felt that you looked or acted out of place with a group of people, you know what it is to be self-conscious. Self-consciousness is the opposite of confidence. The term "self-conscious" has a negative connotation, related to embarrassment, lack of confidence, discomfort.
  8. plebiscite
    a vote determining public opinion on a question
    The plebiscite could be put off no longer; on December 15th, the vote was taken.Egan, Maurice Francis
    Etymologically, the word "plebiscite" means "the common people ("pleb")know ("sci"). This is a word that you probably learned, or will learn, in your social studies class.
  9. unconscionable
    lacking a sense of right conduct
    "Numerous people at the time found it unconscionable that Mr. Arridy was sentenced to death," Ritter said.
    When something is unconscionable, it is inexcusable. The word implies a lack of conscience, or, a lack of awareness or caring about one's conscience.
  10. prescience
    the power to foresee the future
    Melissa did not ask in what her mother was vindicated; she had a dull prescience of trouble.Graham, Margaret Collier
    Because "pre-" means "before," the word "prescience" refers to having knowledge beforehand. But the word "prescience" is usually used in a less occult way than words like "omen" and "premonition." A prescient person may know things before they actually happen, but that is probably more because she has well-developed intuition than supernatural powers.
