Language is a systematic means of communication that employs sound or conventional symbols. Using a foreign language can be problematic when attempting to communicate or translate written or spoken language from one's native language due to structural differences between languages. Among the most widely spoken languages in the world, English is understood by approximately half of the global population, though it is neither an official nor a second language in our country. Nonetheless, due to its significance, it is often taught as a foreign language at schools, institutes, and universities. As previously mentioned, Pashto, our language, shares both structural similarities and differences with English, which can pose challenges for learners. To address these difficulties in learning English, this paper presents a contrastive analysis of English and Pashto adjectives, examining the similarities and differences between them. The study employs a descriptive and contrastive methodology.
