2. Used to form the ordinal numeral when the final term of the spelled number is not “first”, “second”, or “third”.

   the 4th/Fourth of July

   • 2025 August 21, Allison Williams, “I Braved Washington’s First In-N-Out Burger Line”, in Seattle Met‎^[1], archived from the original on 28 August 2025:

     Washington’s first outpost of the California-born burger joint opened Wednesday after long anticipation and a few fake-outs (like the prank sign someone posted in Wallingford in June). Problem is, it’s located in Ridgefield, a suburb of Vancouver, Washington. […] Ridgefield is the 424th location.

   1. (mathematics) Used to form a term denoting the ordinal numeral corresponding to the value, being a natural number, of a mathematical expression.

      The $n$th term of a geometrical progression whose first term is $a$ and common ratio is $r$ is given by $a{r}^{n-1}$.

4. Used to form the denominator of a fraction.

   one seventh; three tenths

Usage notes

• Some numbers undergo a change in spelling: ‎five + ‎-th → ‎fifth, ‎eight + ‎-th → ‎eighth, ‎nine + ‎-th → ‎ninth, ‎twenty + ‎-th → ‎twentieth. See -eth
• Use of this suffix with numbers ending in one, two, or three is occasionally heard in speech, particularly in forming fractions (**thirty-twoth) but is considered highly nonstandard.
• In older texts, this suffix, and the other suffixes for forming ordinals, may be seen written as superscripts: 1^st, 2^nd, 3^rd, 4^th, 5^th. 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.
