Your question supposes that "most native Americans" used the same words and spoke the same language, which is a false assumption.
By "corn" I guess you mean zea mays or the maize plant, since the English word "corn" means cereal crops such as wheat, barley, oats and rye.
Some of the many hundreds of completely different words for maize in native American languages are:
Taino.............................mahiz (first recorded in 1555)
Ojibwa...........................mandaamin
Navajo...........................naadaa
Lenape (Delaware)........chasquem
Powhatan......................pohcuwtoah
Inca (Quechua)..............chuqllu
Aztec (Nahuatl)..............centli
Choctaw.........................tanchi
Mohawk..........................onenhste
Cherokee........................selu
Abenaki..........................skamon
Maliseet..........................wiwonaqotasik
Massachusetts...............weatchimin
Pequot...........................wewautchemins
Narragansett..................accoquiss
Mohegan........................wiwáhcum or wiwáhcumunsh
Sahaptin (Yakama).........sit'xwswáakul or sat'xwswaakul
