Top 10 Longest Words In The English Language

blog author name

Table of Contents

English is a funny language – at least, that’s what most believe. We aim to differ! The language is the most intriguing dialect spoken. 

Every word spoken/read/heard teaches us something valuable! 

Overall, it contains over 750,000 words, each describing something. Plus, every word comprises a dozen different synonyms (maybe more), thus presenting an endless list to learn.

Most English exponents recommend using simple, small, known words to communicate. The other person understands easy words clearly and responds better and quicker.

However (as proud nerds of the 21st century), it’s our academic duty to dig deeper into the language and uncover its hidden gems.

So, buckle up, nerds!
