Horror aequi

Horror aequi,[a] or avoidance of identity,[2]: 100  is a linguistic principle that language users have psychological[3]: 266  or physiological[1]: 51  motives or limits on cognitive planning[1]: 51  to avoid repetition of identical linguistic structures.

The term originated in 1909 in Karl Brugmann,[4]: 219  who used it to explain dissimilation,[3]: 266  the tendency for similar consonants or vowels in a word to become less similar,[5]: 146  which can often be chalked up to simply "euphony".[4]: 219  Today, however, the term is usually applied instead to grammatical elements or structures.[4]: 219 

One of the most widely cited definitions[6]: 39 [7]: 71  is that of Günter Rohdenburg: "the horror aequi principle involves the widespread (and presumably universal) tendency to avoid the use of formally (near-)identical and (near-)adjacent (non-coordinate) grammatical elements or structures."[8]: 205 

In the study of phonology, such avoidance falls under the obligatory contour principle,[2]: 100  which holds that certain consecutive identical sounds are not permitted[9][10]: 383–84  (such as in Mandarin Chinese, where two third tones are not used consecutively[11]: 104 ).

The term horror aequi is sometimes extended to the stylistic preference to avoid repeating the same word in a given text.[12]
