Arabic is one of the most widespread languages in the world that helped in preserving the Arab civilization and influenced many languages, which borrowed thousands of words from it. Some languages also adopted the Arabic letters in their writing systems. Arab scholars were interested in documenting its vocabulary starting from the ages of the first Islamic-Arab civilization. Al-Khalil ibn Ahmad al-Farahidi (died in 170 AH) was the author of the first Arabic thesaurus.
On the occasion of celebrating Doha as the Capital of Islamic Culture 2021, this lecture will highlight the story of “Kitab al-'Ayn” (Al-Ain Thesaurus), the methodology that al-Farahidi invented to analyze and collect its vocabulary, the listing approach he followed, and the features of this thesaurus. Moreover, this talk will feature the linguistic richness of Arabic and the origins of its vocabulary.
