This is a list of long words; words 20 characters or longer.

(Please note that departmentalizations, compartmentalizations, and comparmentalization are 20 or 21 letters (depending on the word length) but does not have the prompts IN, NO, SE, ER, ES, H, IS, or LE.)

(2nd note: PSYCHOPHYSICOTHERAPEUTICS DOES NOT WORK I TESTED IT MANY TIMES AND SPELLED IT CORRECTLY BUT IT DOESN'T WORK YOU NEED TO TEST A WORD BEFORE PUTTING IT IN THE LONG WORDS SECTION!)

Notes for Contributors

 * If there is a "-", "+", or "=" after a word, it means there is a word somewhat similar to it that has a shorter, longer, or equal length than it.
 * If you want to test if a word works or not, go to the OMG GO! Discord server and then go to lame bot. It is 100% reliable!
