The wrd “OK” is the mst frequently spken all-purpse expressin n the planet.The term was brn during a 19th-century abbreviatin① craze and went n t internatinal fame with its wn hand gesture②.Last year,Henry Nass,a 64-year-ld retired English teacher,a New Yrker had spent the last few weeks handing ut cards champining “Glbal OK Day” in advance f the cming anniversary③.
“N matter where peple are frm they use the wrd ‘OK’,but they dn’t knw where it cmes frm,”says Nass.“The prblem is because it’s just,yu knw,OK.” The wrd is OK,perhaps,but its histry is definitely better than average.Allen Walker Read traced the tw-letter wrd t 1839,when editrs at the Bstn Mrning Pst signed ff n articles as “all crrect” with a simple wrd “OK”.The wrd made it int print n March 23 f that year,during an article against a rival editr in Prvidence wh had stated wrngly that a band f Bstnians heading t New Yrk wuld pass thrugh the Rhde Island capital.
