Which Is Longest Word In English Language?

Languages can be fun and difficult to learn at the same time. Some common challenges faced include getting the spelling right, pronunciation and grammar.

Just look at a thick dictionary and you will know the challenges therein.

Things become even more difficult when dealing with complex words or ones that are too long. In English language, the longest word has 189,819 letters. Of course, it won't be mentioned here, as it will take several pages to publish it. The largest word in English language with 189,819 letters describes the chemical composition of Titin, which is the largest known protein. Second largest word in English language has 1,909 letters.
