Correct spelling for the English word "Jemayka" is [d͡ʒˈɛme͡ɪkə], [dʒˈɛmeɪkə], [dʒ_ˈɛ_m_eɪ_k_ə] (IPA phonetic alphabet).
The word "Jamaica" has its roots in the Arawakan language, specifically the Taino dialect spoken by the indigenous people who inhabited the island before European colonization. When the Spanish arrived in the 15th century, they encountered the Taino people and their inhabited island, which they referred to as "Xaymaca" or "Xamayca".
The exact meaning of "Xaymaca" is not fully agreed upon, but it is generally believed to be derived from the Arawakan words "xayam" or "yam", meaning "land of wood and water". This description referred to the abundance of forests and rivers on the island.
With time, as English became the dominant language after the British took control of the island from the Spanish, the pronunciation and spelling of "Xaymaca" gradually transformed into "Jamaica" as it is known today.
