Do not translate idioms word by word. Burn the midnight oil does not mean burning real oil. It means studying or working late.
Phrase: Burn the midnight oil
Simple meaning: Work late at night.
Example sentence: She burned the midnight oil to finish her project.
Using the wrong preposition
Say brush up on grammar, not brush up grammar. Say read up on a topic, not read up a topic.
Phrase: Brush up on
Simple meaning: Review and improve.
Example sentence: I need to brush up on my spelling.
Mixing similar idioms
Learn by heart and know by heart are close, but they work slightly differently. Learn by heart focuses on the process of memorizing. Know by heart means you already remember it well.
Phrase: Learn by heart
Simple meaning: Memorize.
Example sentence: I learned the speech by heart.
Phrase: Know by heart
Simple meaning: Remember completely.
Example sentence: I know the speech by heart now.
Overusing idioms
Too many idioms can make writing sound unnatural. Use one or two strong expressions where they fit. Clear meaning matters more than decoration.

Simple meaning: Start understanding.
Example sentence: I got the hang of essay writing after regular practice.
