  • n. Knowledge imparted; edifying discourse or precepts; teaching.
  • n. Direction given; order; command; mandate: commonly in the plural.
  • n. Synonyms 1 and 2. Training, Discipline, Nurture, Cultivation, Instruction, Teaching, Education; indoctrination, schooling, breeding, advice, counsel. Training is the development of the mind or character or both, or some faculty, at some length, by exercise, as a soldier is trained or drilled. Discipline is essentially the same as training, but more severe. Nurture, by its derivation, expresses a tender, continuous, and protracted training, beginning at an early age. Cultivation, in the active sense, is often used of the training, discipline, or development of some single department of the nature: as, the cultivation of the understanding, the taste, the conscience. (See culture.) Teaching is the general word for the imparting of knowledge: as, the profession of teaching. Instruction has the imparting of knowledge for its object, but emphasizes, more than teaching, the employment of orderly arrangement in the things taught. Tuition is the most external or formal of these words, representing the act. Education is the largest word of all the list, having for its object, like training and discipline, the development of the powers of the man, but generally also a symmetrical development of the whole man, the mind and the moral nature, by instruction, exercise, etc. Education is the word chosen to express the best ideas that men have of the process of teaching and discipline that shall make the wisest, noblest, and most effective kind of man.
