Simplification
By far the most common form of language reform, simplification involves spelling simplification (cf. spelling reform); however, inflection, syntax, vocabulary and word formation can all be simplified in addition. For example, in English, there are many prefixes that mean "the opposite of", e.g. un-, in-/im-, a(n)-, de-, etc. A language reform might propose to eliminate all these miscellaneous prefixes and replace them by just one, say un-. On top of this, there are words such as "good" and "bad" that roughly mean the opposite of each other, but would be better (in terms of simplicity) portrayed as "good" and "ungood", dropping "bad" from the language altogether.
However, the most common form of simplification is the adoption of new spelling reforms. Several major world languages have undergone wholesale spelling reforms: Spanish (in the 18th century), Portuguese (in 1911 and 1945, in Portugal, in 1943 and 1971 in Brazil, and in 2009 in all countries), German (in 1901/02 and 1996/98), Irish in 1948 and Russian (in 1708 and 1919).
