Ordinal numbers tell us the position of something.

The idea

The first three are first, second and third. Many others add -th: fourth; spelling can change, as in fifth. Dates may be written 5 May or May 5 and spoken with an ordinal.

Examples

  • Our room is on the first floor.
  • The second bus leaves at nine.
  • Her birthday is on the third of May.
  • The fourth door is blue.
  • The meeting is on June fifth.
  • The tenth page has a map.

Watch out

Do not use the cardinal five for a position: use fifth.
