Common Mistakes to Avoid

1. Using “extremely” everywhere.
Replacing “extremely hot” with “scorching” or “sweltering” is often stronger than adding an adverb.

2. Choosing a formal word in casual writing.
“Inordinate” can sound stiff in a text message. “Way too much” may fit better.

3. Mixing up “extreme” and “excessive.”
Extreme means at the far end of a scale. Excessive means beyond a reasonable limit. A strong storm may be extreme, but only too much food is excessive.

4. Using negative words for positive ideas.
“Terrible” and “dire” suit bad situations. Use extraordinary or exceptional for good ones.

5. Overusing informal words.
Words like insane work in conversation but may weaken academic or professional writing.

6. Ignoring collocations.
Some pairings sound natural: severe weather, drastic measures, utmost respect. Others sound odd: drastic respect, utmost weather.
