Gestation


Definition:

  • (n.) The act of wearing (clothes or ornaments).
  • (n.) The act of carrying young in the womb from conception to delivery; pregnancy.
  • (n.) Exercise in which one is borne or carried, as on horseback, or in a carriage, without the exertion of his own powers; passive exercise.
