Academic Vocabulary

Academic does not mean complicated

Compare:

Lots of people think this is a big problem.

with:

Many people consider this a significant problem.

The second version is more suitable in formal writing, but it is still clear and direct.

Academic vocabulary should improve precision, not make your text harder to understand.

Verbs for discussing ideas

Useful verbs include:

Word families

Understanding word families helps you choose the grammatical form your sentence needs.

Basic:

The article talks about why inequality is bad.

More precise:

The article examines the negative consequences of economic inequality.

Another:

Basic:

The results show that the programme worked well.

More academic:

The results indicate that the programme was effective.

The academic version is not necessarily longer. It is more precise.

1. Learn vocabulary in context rather than as isolated words.
2. Notice common academic verbs and nouns when reading.
3. Learn different forms of the same word.
4. Check whether a word matches the strength of your claim.
5. Replace vague expressions when a more precise word is available.
6. Avoid replacing simple words only to sound more advanced.

Mistake: Choosing the longest possible synonym.

Weak:

Better:

The government improved the system.

Clarity is more important than complexity.

Mistake: Using words without understanding their grammatical form.

Incorrect:

This is a significance problem.

Correct:

This is a significant problem.

Mistake: Repeating the same academic word constantly.

The study shows... The study shows... The results show...

Better alternatives may include:

suggests

indicates

demonstrates

depending on the meaning.
