- Excessively conscientious.
1603, John Florio, transl.; Michel de Montaigne, Essayes, printed at London: Edward Blount, OCLC 946730821:, II.33:
- If he were not over consciencious in that under colour of some treatie, parle or accord, to take any advantage of his enemies: he was as little scrupulous, in that "he required no other vertue in his Souldiers but valour" […].
- 2001, James Meikle, The Guardian, 15 March:
- Are you an obsessive lover of routine, overconscientious, and think cleanliness is next to godliness? Beware. You may be nearly twice as likely to die from a heart attack as more laid back friends and colleagues.
