Syn. -- Reform; amendment; correction; rectification. -- Reformation, Reform. Reformation is a more thorough and comprehensive change than reform. It is applied to subjects that are more important, and results in changes which are more lasting. A reformation involves, and is followed by, many particular reforms. “The pagan converts mention this great reformation of those who had been the greatest sinners, with that sudden and surprising change which the Christian religion made in the lives of the most profligate.” Addison. “A variety of schemes, founded in visionary and impracticable ideas of reform, were suddenly produced.” Pitt.
