Farsi (Persian) falls into the category researchers call a "less commonly taught language" (LCTL), which means fewer ready-made courses and materials exist than for languages like Spanish, but the same evidence-based study strategies that work for other languages — intensive structured instruction, spaced-repetition flashcards, and grammar-focused input at the beginner stage — apply directly to it. Realistically, expect proficiency to build gradually and in stages regardless of study format (in person or online), and lean on tools built specifically for less-common languages, including AI chatbots, since Farsi has less commercial course material than languages like Spanish or French.
Answered for language learning in general. No specific language was set for this question, so the findings are drawn from general second-language research rather than one language’s literature.
Persian is officially grouped with languages like Arabic, Hindi, and Uzbek as a 'less commonly taught language' (LCTL) in US higher education research, meaning materials, textbooks, and trained teachers are less abundant than for languages like Spanish or French.1,7,9,11
In plain terms
In a large study tracking speaking ability before and after intensive summer courses in 14 less-commonly-taught languages including Persian, complete beginners made the biggest proportional gains of any level, moving from no ability to roughly an 'Intermediate Low to Intermediate Mid' conversational level after one intensive level of study.1
In plain terms
The same study found no significant difference in speaking-proficiency outcomes between students who took intensive language programs face-to-face versus fully online, suggesting a beginner does not need to be near an in-person Farsi class to make real progress.1
Flashcard systems that space out review of words over time (rather than cramming) have repeatedly been shown to improve vocabulary retention for absolute beginners in other under-resourced or non-Roman-script languages, including one study where beginner Hindi students built personalized decks covering script, pronunciation, and vocabulary, and another where beginner Spanish students who used such a tool regularly performed better by semester's end.2,3,8
In plain terms
Example
Beginners who picked their own vocabulary and made their own example sentences or images remembered new words better and forgot them more slowly than beginners given identical teacher-chosen material, in a study of beginning Chinese learners.12
Example
Across a meta-analysis of instructional studies with Persian-speaking learners, teaching methods that let learners absorb correct grammar patterns through exposure ('input-based' instruction) worked better than methods requiring immediate production for the simpler grammar points typical of early study, while producing and practicing the language became more valuable as sentences got more complex.10
In plain terms
Example
Research on beginning-level foreign language teaching found that comparing the new language to the learner's native language, and even using some native-language translation and explanation, speeds up early comprehension rather than holding learners back, especially for adult beginners with almost no vocabulary yet in the target language.6
Learners' other known languages measurably shape how they process a new one, whether helping (through shared vocabulary or structures) or causing predictable errors (through mismatched grammar patterns), a pattern documented in bilingual and multilingual learners of Persian, English, and other language pairs.4,5
In plain terms
Example
AI chatbots and generative AI tools are increasingly used to give less-commonly-taught-language learners a conversation partner and extra practice materials that would otherwise be hard to find, and one study of an AI chatbot used for grammar practice in Korean (another LCTL) found it helped lower-proficiency learners the most; however, AI systems perform less reliably and less authentically for lower-resource languages than for languages like English or Spanish.7,13
