fortyeth
fortyeth is not a recognized word in the English language. It appears to be a misspelling or an unconventional alteration of the word "fortieth". The correct ordinal form of forty is fortieth, indicating the position of something that comes after thirty-ninth and before forty-first in a sequence. For example, one might refer to the fortieth anniversary of an event or the fortieth person in line. The inclusion of the "e" in "fortyeth" is not standard grammatical practice. The correct spelling adheres to established English orthography for ordinal numbers derived from tens. When referring to the numerical order of forty, the correct term is fortieth. This applies to all contexts where the concept of order or sequence is being expressed.
