What are Ordinal Numbers and their Abbreviations?
Ordinal numbers are a type of number used to indicate the position or order of something in a series. For example, first, second, third, fourth, and so on. They are denoted by adding "-th" to the end of the cardinal number (one, two, three, etc.).
The following is a list of ordinal numbers in English from 1 to 100:
Ordinal Numbers 1-20
1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th.
Note that the first three ordinal numbers (1st, 2nd, and 3rd) have irregular spellings. After the 20th, the pattern repeats with the addition of "-ty" (twenty, thirty, forty, etc.) to the cardinal number and then adding "-first," "-second," etc. to form the ordinal number.
Ordinal Numbers 21-100
21st, 22nd, 23rd, 24th, 25th, 26th, 27th, 28th, 29th, 30th, 31st, 32nd, 33rd, 34th, 35th, 36th, 37th, 38th, 39th, 40th, 41st, 42nd, 43rd, 44th, 45th, 46th, 47th, 48th, 49th, 50th, 51st, 52nd, 53rd, 54th, 55th, 56th, 57th, 58th, 59th, 60th, 61st, 62nd, 63rd, 64th, 65th, 66th, 67th, 68th, 69th, 70th, 71st, 72nd, 73rd, 74th, 75th, 76th, 77th, 78th, 79th, 80th, 81st, 82nd, 83rd, 84th, 85th, 86th, 87th, 88th, 89th, 90th, 91st, 92nd, 93rd, 94th, 95th, 96th, 97th, 98th, 99th, 100th.
After the 20th, the ordinal numbers follow a consistent pattern of adding "-ty" to the cardinal number and then adding "-first," "-second," etc. until the 100th.
