Reform means the improvement or amendment of what is wrong, corrupt, unsatisfactory, etc. The use of the word in this way emerges in the late 18th century and is believed to originate from Christopher Wyvill’s Association movement which identified “Parliamentary Reform” as its primary aim.
Reform is generally distinguished from revolution. The latter means basic or radical change; whereas reform may be no more than fine tuning, or at most redressing serious wrongs without altering the fundamentals of the system. Reform seeks to improve the system as it stands, never to overthrow it wholesale. Radicals on the other hand, seek to improve the system, but try to overthrow whether it be the government or a group of people themselves.
A note about spelling: when used to describe something which is physically formed again, such as re-casting it in a mold/mould, or a band that gets back together, the proper term is re-form (with a hyphen), not "reform".
