The sense of "wholeness, perfect condition" is attested from mid-15c.; that of "soundness of moral principle and character; entire uprightness or fidelity, especially in regard to truth and fair dealing" is by 1540s.

"wholeness, completeness, state of being entire or whole," also entierty, mid-14c., enterete, intierty, from Anglo-French entiertie, Old French entiereté "totality, entirety; integrity, purity," from Latin integritatem (nominative integritas) "completeness, soundness, integrity," from integer (see integer).

"tried virtue or integrity, strict honesty," early 15c., probite, from Old French probité, from Latin probitatem (nominative probitas) "uprightness, honesty," from probus "worthy, good" (see prove).

"state or character of being right" in any sense, Old English rehtnisse, rihtnesse "uprightness, integrity," also the fact of being straight; see right (adj.1) + -ness. From 1560s as "correctness, accuracy." 

late 14c., "disgrace, shame, want of honor," from Old French deshonesté (13c., Modern French deshonnéteté) "dishonor, impropriety," from des- (see dis-) + Latin honestatem (nominative honestas) "honorableness," from honestus "honorable; deserving honor, respectable," from honos "honor, dignity, office, reputation," which is of unknown origin. Meaning "want of honesty, lack of integrity," the main modern sense, is recorded from 1590s.

c. 1300, dismembren, "to cut off the limbs of," also figuratively "to scatter, disperse, divide into parts or sections so as to destroy the integrity," from Old French desmembrer (11c., Modern French démembrer), from Medieval Latin dismembrare "tear limb from limb; castrate," from Latin de "take away" (see de-) + membrum "limb" (see member). Related: Dismembered; dismembering.

late 14c., "disgraceful, shameful, without honesty or integrity; unjust, unfair, disposed to deceive or cheat; unmodest, unchaste," from Old French deshoneste (13c., Modern French déshonnête) "dishonorable, horrible, indecent," perhaps from a Medieval Latin or Gallo-Roman compound of Latin dis- "not" (see dis-) + honestus "honorable; deserving honor, respectable," from honos "honor, dignity, office, reputation," which is of unknown origin. The Latin formation was dehonestus. Related: Dishonestly.
