Heterogram (literary studies)
A heterogram in the understanding of literary studies is a text (word or sentence) in which each letter used appears only once, i.e. each letter is “different” from the others. The heterogram is one of the artistic forms of expression of Lettrism and can be found in the poems of Dadaism by Raoul Hausmann and later in the poems of Concrete Poetry by Ernst Jandl .
Examples from the non-literary area:
- Fix coin shelf book
- Dialect research , according to the vocabulary of the University of Leipzig, the longest real word without letter repetition (16 letters)
- Heating oil recoil damping (24 letters), a made-up word and winner of a competition organized by the Society for German Language
A special and extreme form of the heterogram is the panheterogram, in which each letter of the alphabet appears exactly once, while in the ordinary heterogram it is sufficient to use only part of the alphabet without letter repetition . The panheterogram is also a special form of the pangram , which in turn is defined as a word or sentence in which each letter of the alphabet occurs at least once : if it occurs exactly once, it is referred to as a real pangram or a panheterogram, while a pangram in the following It makes sense that individual letters can also be repeated without having to comply with a specific scheme.
The heterogram is also a sub-type of the isogram , which is defined by the fact that its letters (part or the entire alphabet) appear in the same number: in the case of the heterogram, this number = 1.
