Kowtow, which is borrowed from kau tau in Cantonese (koutou in Mandarin Chinese), is the act of deep respect shown by prostration.
“It is a damn poor mind indeed which can't think of at least two ways to spell any word.” - Andrew Jackson
Heard a great story about Jackson turning the table on his political foes. They arranged for him to win an award, the acceptance speech for which was traditionally given in Latin (which he did not speak). Jackson accepted the award, showed up and said ‘’E pluribus unum, my friends. Sine qua non.” Hilarious.
