The Longest Words

Dear Teachers,

I'd like to get the 'breakdown' of the longest words.

antidisestablishmentarianism

Thank You!

Doyou mean like this?
antidisestablishmentarianism
anti + dis+ establish + ment + arian + ism
against + negative + set up + noun ending + person + noun ending??

"foccinoccinihillipillification" is spelt thus. Of the words that you listed, only "antidisestablishmentarianism" is in common use. If you're looking for really long words, then chemical names, particularly in organic chemistry, can be of any length. If you add another chemical group, you have to add it to the name specifying exactly where you put it.

I think the fifth one is probably a misprint. The closest I found (in Dorland's Online Medical Dictionary) were hepaticocholangiojejunostomy (the surgical creation of a communication between the hepatic duct, another biliary duct, and the jejunum) and hepaticocholedochostomy (the surgical anastomosis of the hepatic duct and the common bile duct).

Good Day! Tdol and Ronbee, How do you do and MikeNewYork as well?

I started this thread.
By searching half days of my holiday, I found out this:
PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS
PNEUMONO-ULTRA-MICROSCOPIC-SILICO-VOLCANO-CONIOSIS

FLOCCINAUCINIHILIPILIFICATION
flocci-nauci-nihili-pil-ification

I can read some of the prefix and roots
Antipericatametaanaparcircumvolutiorectumgustpoops
anti-peri-cata-meta-ana-par-circum-voluti-o-rectum-gust-poops

osseocaynisanguineoviscericartilagininervomedullar y
osseo-cayni(?)-sanguine-o-visceri-cartilag-ini(?)-merv(?)-medullary(?)

aequeosalinocalcalinoceraceoaluminosocupreovitriol ie
aeque-o-salin-o-calcalin(?)-o-cerace(?)-o-alumin-o-socupre(?)-vitriolie

hepaticocholecystostcholecystntenterostomy
hepatic-o-cholecystost-cholecystnt-enterostomy
note: cholecystis means inflammation of the gall bladder, so I guess that 'cholecyst' means gall bladder.

Here are the meanings of the longest words:

How about this one? Many say it is the longest word in English (it's a protein):

I thinkI've spelt it correctly.

[RonBee]

That's a mouthful. (And a half.)

There are bigger proteins. Nobody has bothered writing their sequence.
