Do any words have three or more correct spellings? [closed]
Solution 1:
Here's a four-variant
aerie/aery/eyrie/eyry

https://en.wiktionary.org/wiki/eyrie#English
Though some dictionaries only list 3:

or 2:

Solution 2:
There are ketchup, catsup, and catchup, all in the Merriam-Webster dictionary. And in fact, looking at Ngrams, all three spellings were reasonably common between 1910 and 1960, although catchup has become relatively rare today.
