Abstract:
This paper provides an Optimality-Theoretic account of dissimilation in standard
Persian as well as some other accents and dialects of Persian. As such, this work starts
by introducing Optimality Theory (henceforth OT) and its basic concepts and then it
investigates dissimilation in this framework. It argues for the superiority of OT over
derivational approaches regarding a case in which both dissimilation and assimilation,
with no clear feeding order, are involved.
در این مقاله فرایند نا همگونی در فارسی و چند لهجه و گویش دیگر فارسی در چهارچوب نظریه
بهینگی مورد تحلیل قرار میگیرد؛ ابتدا به معرفی نظریه بهینگی و بیان اصول و مبانی آن پرداخته
می شود، سپس فرایند نا همگونی در این چهار چوب مورد بررسی قرار می گیرد. در این مقاله استدلال
می شود که نظریه بهینگی بر رویکردهای اشتقاقی برتری دارد. این استدلال مبتنی بر یکی از مواردی
است که در آن هر دو فرایند همگونی و ناهمگونی به گونه ای رخ می دهد که مشخص نیست کدام یک
زمینه چین دیگری بوده است.

Machine summary:
"Since in the process of dissimilation in the feature [continuant], [-continuant] affricates change to [+continuant] fricatives, the faithfulness constraint that militates against any change in the value for the feature [continuant] in the output is IDENT[cont].
Tableau (3) (رجوع شود به تصویر صفحه) As displayed in Tableau (3), the faithful candidate fatally violates the undominated constraint because it contains [dY] plus [d]sequence.
(11) *AFPLAL, IDONSLAR>> AGREE [voice] >> IDENT [cont], IDENT [voice] Tableau (4) (رجوع شود به تصویر صفحه) Tableau (4) demonstrates two processes of assimilation and dissimilation undergone by the output [moRtame>] from its corresponding input /mocYtame>/.
3-1-2 Dissimilation in the feature [Voice] In Hamedani1 accent, the voiceless plosive /t/ changes to its voiced counterpart in the environment after a voiceless consonant (Kambuziya, 2007: 388-390) (رجوع شود به تصویر صفحه) The words that undergo this dissimilation process are divided into groups (a) and (b) in terms of their syllable structures.
Tableau(6) (رجوع شود به تصویر صفحه) This dissimilation process is the effect of the ⎡ low ⎤ undominated markedness constraint * ⎢ ⎥ -2 −back which prohibits a sequence of two syllables whose nuclei are filled with the [ low] and [- back] vowel [a].
With regard to the data from other accents and dialects of Persian, we discussed our dealing with cases of dissimilation in features [voice] and [lateral] as well as vowel disharmony each being the effect of markedness constraints *[-voice]-2, *[+lateral]-2, and ⎡ low ⎤ * ⎢ ⎥ -2 respectively."
