With typhoon season in full swing, let’s disentangle the etymologies circling the word. Hurricanes (in the Atlantic and northeastern Pacific oceans), cyclones (Indian Ocean) and typhoons (northwestern Pacific) are different names given to the same weather phenomenon depending on where they occur. The origin of the word “typhoon” is commonly ascribed to the Chinese 颱風 – “great wind” ( daaihfùng in Cantonese). Hong Kong on standby for third typhoon in two weeks, as Mawar approaches But wait … a clear origin lies in Arabic: possibly derived from “ t ā fa ” (“to turn round”), “ el-t ū f ā n ” occurs in two passages of the Koran, describing a flood or storm, and the deluge, with t ū f ā n designating a storm of the seas between Arabia and China. This suggests that, if t ū f ā n is derived, as some hold (though others point to the Aramaic “ t ā f ”), from the Greek “ typhon ” ( τῡϕῶ ν ) – the mythological hundred-headed, flame-breathing giant, father of the winds – via maritime trade, or the translations of Aristotle, it would have entered Arabic no later than the seventh century. It then spread to Persian, as “ tufân ” (and the Turkish “ tayfun ”), and thereafter to Urdu, as t ū f ā n , the language heavily influenced by Arabic and Persian, through late-first-millennium Muslim conquests, and subsequent 12th- to 16th-century Persianised Central Asian dynasties on the Indian subcontinent. From there, the word appeared in the writings of European travellers in the East Indies: the Portuguese “ tufão ” is the earliest printed mention, found in 16th-century traveller-writer Fernão Mendes Pinto’s autobiographical memoir Peregrinação (“pilgrimage”). This came from Urdu, though some believe that, in the longstanding maritime trade network of the Indian Ocean, Portuguese explorers got it directly from the Arab pilots. Subsequent European colonisers adopted Portuguese borrowings. “ Touffon ” first appeared in a 1588 English translation of Venetian merchant-traveller Cesare Federici’s account; 17th- and 18th-century English writings employ “ tufan ”, “ tuffon ”, “ toofan ” and “ tuffoon ”. Could the word have developed independently, in parallel, in Greek/Arabic and Chinese? An answer lies in the earliest mention and scientific description of typhoons, found in Chinese literature: Nan Yue Zhi (“Book of the Southern Yue Region”, AD470) uses “ jufeng ” – “ ju ” being a wind or storm from all four directions. Commonly used in the Tang dynasty (618-907) and proliferating during the Northern Song dynasty (960-1127), it was jufeng – not “ taifeng ” – that was an integral part of Chinese vocabulary. Modern Chinese probably reanalysed this to “ taifung ”, following Arabic/Urdu, through later (perhaps 15th-century) regional maritime trade and contact. This reinforced and modified the English usage: 18th- to 19th-century writings about the China coast start reflecting this pronunciation, with the spelling “tiffoon”, which, possibly by association with Greek typhon (“whirlwind”), settled by the early 1800s to “tyfoon” and, finally, “typhoon”.
