Apostrophe and Possession is crucial for showing ownership and forming contractions in English. Mastering this small but powerful punctuation mark can significantly enhance the clarity and professionalism of your writing.
Examples
Example 1
IncorrectThe students books were left on the back table.
BetterThe students' books were left on the back table.
The apostrophe after 'students' indicates that the books belong to the students.
Example 2
IncorrectIts important that the team checks every heading.
BetterIt's important that the team checks every heading.

How It Works
Meaning
An apostrophe is a punctuation mark used to indicate possession or to form contractions by replacing omitted letters.
For possession, use 's with singular nouns (e.g., the manager's report) and s' with plural nouns ending in 's' (e.g., the managers' meeting).
In contractions, apostrophes replace missing letters (e.g., it's for it is). Distinguish between its (possessive) and it's (it is).
At the B2 level, mastering these distinctions enhances clarity and precision in writing.
Use it when
- Indicating ownership by a singular noun or a plural noun ending in 's'.
- Forming contractions to replace missing letters.
- Writing formal and informal texts where clarity is essential.
- Editing your writing to ensure correct punctuation usage.
