Research cutoff: · Updated:More than an accent
In Iran, the phrase “local dialect” can describe quite different things. It may refer to the recognizable pronunciation of Persian in a particular city, or to a speech variety whose grammar and vocabulary differ substantially from Persian. These meanings should not be treated as interchangeable. Linguist Gernot Windfuhr distinguishes popular references to an accent from the broader linguistic study of differences in sound systems, grammar and vocabulary. s1
Persian terminology also requires care. Lahja can refer to an accent, while guyesh is used for a dialect rather than simply a pronunciation pattern. Neither an English label nor a local name, on its own, settles how closely two varieties are related. A useful description therefore identifies the community and locality, explains what kind of variation is involved, and states the basis for its classification. s1
[s1]A geography finer than provincial borders
The scholarly label “Central Dialects” refers to a collection of Iranian varieties documented across central Iran, roughly within the area between Hamadan, Isfahan, Yazd and Tehran. It does not mean the Persian accent of a single central city. Windfuhr relates these varieties to other western Iranian speech groups, including Tati and Talysh, while distinguishing them from more distant relatives. s2
The wider linguistic landscape extends beyond this central grouping. A scholarly overview identifies Semnani and neighboring varieties along the northern edge of the central desert, as well as local varieties in Fars and the south. These include Larestani, speech varieties around Bandar Abbas and Minab, and Bashkardi farther southeast. Such names describe different geographical and linguistic groupings; they are not a list of interchangeable provincial accents. s3
This distinction matters when reading a map. A province may contain several varieties, while related varieties may extend across an administrative boundary. The place name supplies a location, but the linguistic classification requires additional evidence. s2s3
[s2] [s3]Isfahan as a case study
Habib Borjian’s study of Isfahan’s provincial dialects brings together evidence from individual localities, historical texts and linguistic surveys. Its locality-based bibliography includes places such as Abyaneh, Abuzaydabad and Ardestan. This makes the region a useful example of why “the dialect of Isfahan” is too imprecise without further explanation. The Persian spoken in the city and the surrounding varieties studied under the Central Dialects rubric require separate treatment. s4
Documentation is uneven. Borjian describes survey material whose usefulness was limited by recording quality, incomplete publication and problems with surviving field records. A historical record can establish that a variety was documented in a place; it cannot establish how many people speak it there today. s4
The most informative encounter with a local variety begins with specific questions: What do speakers call it? Where and with whom is it used? Is the description based on a recording, a grammatical study or an older written reference? These distinctions preserve the richness of local speech without turning an old linguistic map into an unsupported account of present-day language use. s1s4

limitations
- The inspected scholarship provides historical and classificatory context rather than a comprehensive survey of language use in 2026.
- The page is selective and does not inventory every local variety or settle disputed language-versus-dialect classifications.
- Sources were accessed after the editorial cutoff; the account uses historical scholarship rather than asserting developments after that cutoff.
data gaps
- No comparable annual series of speakers, household transmission or language use for the local varieties discussed was established from the inspected sources.
- Historical locality counts were not converted into current speaker estimates or a time series.
coverage period
Historical documentation and linguistic scholarship published before the editorial cutoff; no current speaker census established.
