definitions & notes only words
  1. subjective
    of a mental act performed entirely within the mind
    One's feelings about tattoos are by definition subjective.
    Slate (May 6, 2013)
    The connection between the prefix "sub-" (under)and "-ject," (throw) is indirect, a little hard to see. To look at something subjectively is to be under the influence of personal opinion, experience, self-serving motivation, or emotion that underlies judgment.
  2. objective
    the goal intended to be attained
    "We have an objective: price stability," he said.
    Reuters (May 23, 2013)
    The word "objective" (literally: "that at which we are thrown") is used as a noun in the example sentence. As a noun, "objective" simply means "goal" and is used interchangeable with the words "goal," "target," or "aim." As an adjective, to be "objective" is to be able to look at something without any personal or emotional attachment, with just the facts thrown at you.
  3. eject
    put out or expel from a place
    Shaw lasted five innings before he was ejected for arguing.
    Seattle Times (May 3, 2013)
    With the prefix "e-" meaning "out," and the root "ject-" meaning "to throw," it's clear to see that the word "eject" means "to throw out." However, when we remove the garbage from the house, we never say that we are "ejecting" it. The word "eject" is usually applied to either a forceful toss-out, or the removal of a member of the group, as in the example sentence.
  4. inject
    force or drive (a fluid or gas) into by piercing
    Meanwhile, the nurse has not missed a beat, injecting several more vaccines.
    Scientific American (May 20, 2013)
    With the prefix "in-" meaning "into," and the root "ject-" meaning "to throw," it's clear to see that the word "inject" means "to throw into," although this word is usually used in a medical sense, in its noun form, "injection," known colloquially as "a shot." Shots, are, after all, thrown in some way, hence the connection.
  5. conjecture
    to believe especially on uncertain or tentative grounds
    Injured skier Lindsay Vonn flew home from Austria on Tiger Woods' private jet, only intensifying conjecture about their relationship.
    Seattle Times (Feb 16, 2013)
    With the prefix "con-" meaning "with," and the root "ject-" meaning "to throw," with a little imagination, we can see how the word "conjecture" derives its meaning of "an informed guess." A conjecture lies somewhere between a hypothesis (an educated guess) and a wild guess: a conjecture is a guess based on some facts thrown together with a hunch or two.
  6. projectile
    a weapon that is forcibly thrown or projected at a target
    The dinosaurs were all-but certainly wiped out by a direct hit by a far smaller projectile 65 million years ago.
    Time (Feb 5, 2013)
    With the prefix "pro-" meaning "forward" and the root "ject-" meaning "to throw," and the suffix "-ile" transforming a noun into a verb, it's clear to see how that word "projectile" means an object that is thrown, usually against a target. Bullets, cannon balls, and paper airplanes are examples of projectiles.
  7. trajectory
    the path followed by an object moving through space
    At first glance it seems to be on an unbroken upward trajectory.
    BBC (May 1, 2013)
    With the prefix "tra-" being a form of the prefix "trans-" meaning "across," and the root "-ject" meaning "to throw," and the suffix "-ory" designating a noun, we can see how the word "trajectory" refers to a path of objects through space. But the word "trajectory" actually denotes more than that: A trajectory is a kind of pre-determined or predictable path, not only of physical objects, but of events in life as well. Key decisions that we make in life are said to set our trajectories.
  8. adjective
    the word class that qualifies nouns
    "It's pretty frustrating, disappointing and all the other similar adjectives," Anderson said.
    Seattle Times (May 18, 2013)
    With the prefix "ad-" meaning "toward," and the root "ject-" meaning "to throw," we can see how the word "adjective" has come to mean a word that is "thrown at," so to speak, a noun.
  9. dejected
    affected or marked by low spirits
    I buttoned up my coat and trudged off, dejected.
    The Guardian (Oct 29, 2012)
    With the prefix "de-" meaning, in this case, "down," and the root "ject-" meaning "to throw," we can see how the word "dejected" means "feeling low." To feel "dejected" is a little different from feeling "depressed." Usually, the word "dejected" is used when one's low spirits may be ascribed to a particular hurtful or disappointing event, while "depressed" usually refers to a more generalized and chronic sorrow.
  10. abject
    most unfortunate or miserable
    And China lifted 300 million from absolute abject poverty into sustainable working class.
    Economist (Apr 24, 2013)
    With the prefix "ab-" meaning "away" and the root "ject-" meaning "to throw," we can see how the word "abject" means, truly, "thrown away." Usually used as an adjective to modify "poverty" ("abject poverty") the word "abject" connotes a hopeless state and is a sad word to even contemplate, especially when applied to large groups of people, which it usually is.
  11. interject
    to insert between other elements
    James Murdoch blanched at the question, but his father interjected: "We were not ever guilty of that," Rupert Murdoch said.
    Wall Street Journal (Jul 19, 2011)
    With the prefix meaning "inter-" meaning "between," and the root "ject-" meaning "to throw," we can see how the word "interject" means "to interrupt."
