Thai spelling reform of 1942 - Wikipedia

The Thai spelling reform of 1942 was initiated by the government of Prime Minister Field Marshal Plaek Phibunsongkhram. The prime minister's office announced a simplification of the Thai alphabet on 29 May 1942. The announcement was published in the Royal Gazette on 1 June 1942.[1][2] The reform was cancelled by the government of Khuang Aphaiwong on 2 August 1944. Following the November 1947 coup, Phibunsongkhram became prime minister for a second time, but did not revive the Thai language reform.
