It isn’t sesquipedalianism, it isn’t pneumonoultramicroscopicsilicovolcanoconiosis, and it definitely isn’t supercalifragilisticexpialidocious. So, what is the most complex word in the English language?

Sometimes, the simple things can be the most complex.

I think the F word is the most versatile.

5:05 Priceless also has 2 meanings that have have different opposite meanings from each other, which makes this even more confusing!

How about how some genius chose to label the very phobia of long words with a 36 letter term.
Hippopotomonstrosesquippedaliophobia. Were they just intentionally and deliberately taking the piss by calling it that?

What appears to be the universality of the roots, "set" and "run," is the causation of place and the elapsing of duration, respectively. They are essential time-space qualifiers.

Wait!🙁 That means complex is also a very complex word 🤓if we can change its definition according to ourselves.😶🌫

The most complex word in the English language is "shit".
It can be the shit you shit, the shit you know, the shit people say, the shit you own, the shit you imbibe, good shit, shit shit, or other shit, or it can just be the shit. Shit, shit's shit!

English speakers say 'set foot,' whereas speakers of the US American dialect say 'stepped foot.' Why?

Words have recently had a paywall effect placed upon them. A Google search is about as good for defining a word as asking an average middle school student. For example, in reality, “cleverness” is defined as the amount of trivial information a person can hold at one time, usually about a certain subject but not always, and “smart” is defined as someone who can think more quickly than average, while “intelligence” is the ability to combine ideas and find out new information due to those combinations. However, if one Googles these terms then they will find very similar and vague definitions given. This information is probably still available to wealthier people through different search results being presented or older dictionaries or by better schooling. I would imagine the three asterisks indicate that the most complex word is “set”. Supercalafradulusticexpialidocious is probably much more specific than the common person thinks it is, like most words. For example, “fantastic” is more literally a word that relates more to something being fantastical or of or relating to fantasy, the genre or mental exercise. “Terrific” was probably used sarcastically until it became colloquial slang as it is in fact more to do with terror. I recently thought about the word “fancy” and how it may have come from some old Northern English slang like “Francie”, which would mean French-like, which at the time would mean upperclass. I hope this interested someone. Chao!

another definition for set is: the god of deserts, storms, disorder, violence, and foreigners in ancient Egyptian religion.

we don't "make" english more complicated to learn, we aren't specifically creating the language in the intention of making it hard to learn, it is just naturally progressing in a way that happens to be, and unfortunately, in hard to learn
