French word 'charivari' stands for a carnivalesque procession with noise and kettle music. The Charivarius section was continued by Nolst Trenité until De Groene was banned by the occupying forces in 1940. Three anthologies Charivari (1913) and Charivaria (1915 and 1916) have been published, as well as five collections under the name Ruize-rijmen (1914-1918), from which an anthology was compiled in 1922, also under the title Ruize-rijmen. His book Is that good Dutch? (Amsterdam, 1940) is one of the best-known language advice books: it reached ten editions and was reprinted in a facsimile in 1998. The column consisted partly of ironic and sometimes cynical rhymes (especially those about the bloodshed of the First World War), partly of an ironic approach to language derailments that Charivarius identified in various publications. Later he went on about running text, citing many examples of errors. He gave colorful names to certain mistakes. For example, a succession of short sentences was called panting style, and he coined the name 'Fnaffers en Fuiters' for language users who wrote 'from' and 'from' to each other. The Chaos "The Chaos" is a poem demonstrating the irregularity of English spelling and pronunciation. It includes about 800 examples of irregular spelling. The first version of 146 lines of text appeared in an appendix to the author's 1920 textbook Drop Your Foreign Accent: engelsche uitspraakoefeningen, but "the most complete and authoritative version ever likely to emerge", published by the Spelling Society in 1993–94, has 274 lines. Aunt Betje The most famous term attributed to Charivarius is the "aunt betje". This is an inversion error, which occurs with compound sentences (after coordinating conjunctions such as and, because, or but). Traditionally, in Dutch the order subject-verb must be the same in both sentences. Charivarius seems to have mentioned the term by name for the first time in his weekly language column in the De (Groene) Amsterdammer. Although some sources place the name in 1940 or 1918, the oldest site is 22 June 1913. Charivarius then writes: “Aunt Betje — why should we keep the name of our old friend silent? – now has again in the NR Ct. written” (“Tante Betje – waartoe zouden wij den naam van onze oude vriendin verzwijgen? – heeft nu weder in de N. R. Ct. geschreven”) Although Charivarius refers here to 'an old friend', and elsewhere states that he named the mistake after an elderly Aunt Betje,
