Incorrect spelling, explanation: when we form ordinal numbers in English we usually add the -th ending to a number, e.g. we have seventh, eleventh, or twentieth. However, the first three numbers are exceptions as we have the 1st, 2nd, and 3rd. Some users of English forget about this rule and they make the mistake of creating the form 81th while the only correct version is 81st.
Correct spelling, explanation: 81st is an ordinal number that appears between eighty and eighty-two. As a full number 81st is spelled as eighty-first. The root of the 81st is, naturally, the word eight, which comes from the Germanic language and appeared for the first time in Old English, in which it had the form ehta.
Definition of 81st:
1. number – it is between 80 and 82;
He was only 81st on the entrance list to the college so he probably won’t get a place there.
