In the month of September 2025, 56 words were added to the Bee lexicon, and 1 word was discontinued, for a net gain of 55 words.
Here's a summary of what came and went, along with a few notes about the month’s pangrams (numbers, types, and more), the lengths of the daily word lists, the rates at which the dreaded/adored -ED and -ING suffixes appeared, how often the BINGO characteristic appeared, center letter distribution, the complete list of pangrams and “Ins and Outs” in the month, and more.

SPECIAL NOTE: SECOND APPEARANCE OF LETTER "S"
The letter S made its second appearance in the Spelling Bee on 2025-09-02.
An extraordinary number of new words – 25 – made their Bee debuts that day, and all of them included the letter S. Of note: 15 of the 25 new words were plurals of words that were already in the Bee lexicon. See the LexiConnexxions report on the letter "S" in the Bee for more details.
18 different center letters were used during the month.

** re: Bee of 2025-09-21: This puzzle was the third time that the letter set F A C I N R T had been used; the earlier instances were on 2019-09-22 (center letter R) and 2019-01-29 (center letter I). The Bee of 2025-09-21 was unusual in that of its four pangrams, only two had been used in the earlier iterations. See the full analysis HERE.
Of the 30 Bee puzzles this month:
7 (23.33%) were based on pangrams and letter sets that had never been used before. These 7 puzzles introduced 13 new pangrams and added a total of 48 new words to the Bee lexicon, an average of 6.86 new words per puzzle.
23 (76.67%) were based on pangrams and letter sets that had been used before.* These 23 puzzles used 36 recycled pangrams and introduced 2 new pangrams,* and added a total of 8 new words to the Bee lexicon, an average of 0.35 new words per puzzle. * NOTE re: New Pangrams Previously Disallowed: The Bee of 2025-09-21 introduced two pangrams (INFARCT, INFRACT) that had been disallowed each of the two times that the letter set had been previously used. The inclusion of a previously-disallowed pangram is very rare, as explained and demonstrated in the LexiConnexxions report "Pangrams Previously Disallowed," which can be read HERE.
Of the 23 puzzles with repeat letter sets and repeat pangrams: 08 letter sets were used for the second time 08 letter sets were used for the third time 06 letter sets were used for the fourth time 01 letter set was used for the fifth time
