kritischeren
Kritischeren is not a standard Dutch word found in major dictionaries. It is sometimes presented or encountered as a comparative form of the adjective kritisch, meaning more critical. In contemporary Dutch, the usual ways to form the comparative are either with the suffix -er, yielding kritischer, or with the periphrastic construction meer kritisch (two words). Therefore, kritischer or meer kritisch are the normal options, while kritischer is common in many contexts and kritischer than kritischer would be. Kritischeren, by contrast, is generally regarded as nonstandard or a misformation.
