How to write ordinal numbers (those denoting order) down in words?

Most ordinal numbers end in "th", so just add "th" to the end of the cardinal number (those denoting quantity, ex: 1 one, 2 two, 3 three, 4 four, ... etc.):

  • cardinal: 4 = four -> ordinal: 4th = fourth
  • cardinal: 7 = seven -> ordinal: 7th = seventh
  • cardinal: 10 = ten -> ordinal: 10th = tenth
  • cardinal: 19 = nineteen -> ordinal: 19th = nineteenth
  • cardinal: 100 = one hundred -> ordinal: 100th = (one) hundredth
  • cardinal: 1,000 = one thousand -> ordinal: 1,000th = (one) thousandth

  • cardinal: 1 = one -> ordinal: first = 1st
  • cardinal: 2 = two -> ordinal: second = 2nd
