I actually had this word in my ‘spelling’ class in 6th grade. That was awhile back, but as far as I am aware it is still the longest word.

pneumonoultramicroscopicsilicavolcanoconiosis is how i remember it being spelled, but that was awhile ago.

Supercalifragilisticexpealadocious? I’m not sure I spelled it correctly or if it’s even a word. Rikitikitimbonosadimbochadabarryrichypepperrypimbo, I’m not too sure about the spelling of this word eith, I could be making it up, I’m not sure, or maybe I read it somewhere.
