Sağlam (2004) investigates the influence of foreign words on Turkish, presenting the extent of borowings from different source languages, known as the "etymological spectrum". The spectrum is considered to be the result of a diversification process. The present paper demonstrates that the etymological spectrum of Turkish abides by a general model that Altmann (1993) deduced for any linguistic rank orders.
Using Quantitative Linguistics as its theoretical context, this paper recognizes that every language in a speech community is subject to permanent diachronic alteration. Special language changes need to be investigated as if they abide by one of the established linguistic laws. The present paper demonstrates that three different processes in Chinese (substitution of voiced obstruents in the Shuang-feng dialect, increase of Chinese characters, increase of word lengths in the history of the Chinese language) follow the so-called logistic law, also known in linguistics as “Piotrowski’s law,” which once again appears to be universal.
