Words with Many Anagrams

Of course, the question of what words are the (single-word) anagrams of other words depends on having a reference list of all words. For this purpose I am using a list of 466,378 words gathered over time. The list has grown by about one-third over the last few years. Some of the additions are actually new words such as covid. On the other hand, I have the impression that many of the added words may be viewed as misspellings of standard words that have come into use. For example abcess appears now to be in use as an alternate spelling of abscess. Other words on the list are archaic spellings of standard words. Regardless, my list may not be regarded as definitive in any way. The following table lists by rows all words having 11 or more anagrams. The first column contains the common length of the words in that row, and the second column gives the number of words in the row.
