Usage notesEdit

  • See -eth
  • When suffixing a spelled number ending on "eight", its final "t" is dropped: eighth; twenty-eighth.
  • In older texts, this suffix, and the other suffixes for forming ordinals, may be seen written as superscripts: 1st, 2nd, 3rd, 4th, 5th. This is considered old-fashioned; the current preference is to write (when not spelling the numbers), 1st, 2nd, 3rd, 4th, 5th.
  • When used to suffix a mathematical expression, a hyphen is sometimes inserted: n-th term.
