These nouns all pertain to what underlies and supports. Base is used broadly in both literal and figurative contexts: the wide base of the pyramid; a party seeking to expand its power base.
Basis is used in a nonphysical sense: "Healthy scepticism is the basis of all accurate observation" (Arthur Conan Doyle).
Foundation often stresses firmness of support for something of relative magnitude: "Our flagrant disregard for the law attacks the foundation of this society" (Peter D. Relic).
Ground is used figuratively, especially in the plural, to mean a justifiable reason: grounds for divorce.
Groundwork usually has the sense of a necessary preliminary: "It [the Universal Declaration of Human Rights] has laid the groundwork for the world's war crimes tribunals" (Hillary Rodham Clinton).
These adjectives mean lacking in dignity or falling short of the standards befitting humans. Base suggests a contemptible, mean-spirited, or selfish lack of human decency: "that liberal obedience, without which your army would be a base rabble" (Edmund Burke).
Something low violates standards of morality, ethics, or propriety: low cunning; a low trick. Abject means degrading or miserable: abject failure; abject poverty. Ignoble means lacking noble qualities, such as elevated moral character: "For my part I think it a less evil that some criminals should escape than that the government should play an ignoble part" (Oliver Wendell Holmes, Jr.).
Mean suggests pettiness, spite, or stinginess: "Never ascribe to an opponent motives meaner than your own" (J.M. Barrie).
Sordid suggests foul, repulsive degradation: "It is through art ... that we can shield ourselves from the sordid perils of actual existence" (Oscar Wilde).
