Help:Reverting

On Wikipedia, reverting means undoing or otherwise negating the effects of one or more edits, which results in the page (or a part of it) being restored to a previous version. Partial reversion involves restoring one part of the page to a previous version, but leaving other contributions intact. Self-reversion is the act of reverting your own edits. Reverting does not always involve the use of the undo tool. Any method of editing that has the practical effect of returning some or all of the page to a previous version counts as a reversion.

Reverting a contribution is sometimes appropriate. However, reverting good-faith actions of other editors can also be disruptive and may lead to the reverter being temporarily blocked from editing. The three-revert rule (part of the edit warring policy) limits the number of times an editor can revert edits (including partial reversions) on a page.
