🇮🇷 Best Persian dictionaries for advanced learners

The everyday lookup tool many Iranians use: two-way Persian-English definitions with spoken pronunciation on a click, a machine translator, and a community question board where you can ask about a phrase nobody has defined. It is free and covers colloquial words that formal dictionaries omit. The interface is Persian-first and heavy with ads, and crowd-sourced answers vary in quality, so verify anything important against Vajehyab or a printed dictionary.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.

Type a word and it returns entries from more than twenty dictionaries side by side, including the monumental Dehkhoda lexicon and Moin, plus Persian-English glosses — the fastest way to see how a word is defined by Persian lexicographers rather than by a translation app. The core lookup is free; a subscription removes limits and ads. The interface is entirely in Persian and the definitions are written for native speakers, so this is a tool for the point where bilingual dictionaries start failing you, not for week one.
