I recently had cause to peruse this article and it introduced me to the word “productionizability”. A noun derived from a verb derived from a noun. It made me cringe.
Related to this, when I was at school the longest word in English was claimed to be “antidisestablishmentarianism”. It disappointed me, because it’s such a construction. Nothing wrong with that per se, but I always wanted to ask, “why stop there?”. Presumably, antidisestablishmentarianismability might refer to the ease with which something can be claimed to be antidisestablishmentarianism.
Anyway, the longest word in English is pneumonoultramicroscopicsilicovolcanoconiosis. Maybe.
