It might surprise you but one of the longest words in the world is not some obscure scientific term or difficult philosophical concept. It’s actually “antidisestablishmentarianism”!

At 28 letters long, this word is a mouthful! But what does it mean?

The word “antidisestablishmentarianism” was first used in 1828 by English politician and theologian Lord John Russell. It is a compound word formed from the Latin prefix “ante” (before) and the English word “disestablishment” (the act of dissolving an established church).

So, “antidisestablishmentarianism” can be translated as “the belief that it is desirable to maintain the established church in its present form”.

In today’s society, the word “antidisestablishmentarianism” has mostly fallen out of use. But it still remains an important part of English history and culture. And who knows? It might one day be resurrected to describe a new political movement or social trend!

What about the longest words in English that are still being used?

“Floccinaucinihilipilification”, “antidisestablishmentarianism”, and “supercalifragilisticexpialidocious” are all in the top 10!

  • If you are looking for words using x, y, and z in alphabetical order, pick up a Chemistry book. All the words using ‘oxy’ somewhere can be helpful. Here are some that our Chemistry assignment writers often use:

  • “deoxygenize” which means “to remove molecular oxygen”
  • “methoxybenzene” which is “the chemical composition of Anisole – an organic compound whose derivatives are often found in natural and artificial fragrances”

  • Our assignment writers have years of experience in writing high-quality papers for our students. They suggest that many students make the mistake of using many simple terms in their writing. It gives an ‘elementary’ feel to their writing. While longer, more complex words are not necessarily better than short and simple ones, a good academic paper uses concise and varied language.

For example: Instead of ‘bad result’ you can say ‘ poor result’.

Some other words that sound better in an academic paper are:

  1. Big sample: Large sample
  2. Gets attention: Receives attention
  3. Gives an overview: Presents/Provides an overview
  4. Good example: Prime example
  5. Below figure shows: Below figure illustrates/demonstrates
  • They also suggest you replace phrasal verbs with one-word alternatives.

For example, you can replace ‘add up’ with ‘calculate’.Here’s how you can use it in a sentence:

‘Riley added up the number of marks in the English paper’ can be changed to ‘Riley calculated the number of marks in the English paper’.

Here is a quick table of 10 most-common phrasal verbs students use and their one-word alternatives:

  1. buy out: purchase
  2. call off: cancel
  3. carry on: continue
  4. carry out: execute
  5. find out: discover
  6. get over with: complete
  7. get across: communicate
  8. hold up: delay
  9. leave out: omit
  10. pass out (surveys, samples, etc.): distribute
  • Using vague terms can make your academic paper sound imprecise. Hence, GoAssignmentHelp online academic reviewing experts always recommend students to be as specific as possible.

For example:

  1. Instead of ‘stuff’, you should use specific terms like ‘belongings’ or ‘personal effects’ or ‘concepts.
  2. Instead of ‘things’, you might write ‘details’, ‘findings’, ‘recommendations’, etc.
  3. Instead of ‘a long time’, it’s always better to mention how much time, such as ‘for 33 years’ or ‘for seven weeks’.
