Common Mistakes People Make

Mistake 1: Using an Apostrophe for a Plural

Mistake 2: Forgetting the Apostrophe for Possession
❌ Thursdays meeting starts at noon.
✅ Thursday’s meeting starts at noon.
The meeting belongs to Thursday.
Mistake 3: Saying “Every Thursdays”
❌ Every Thursdays
✅ Every Thursday
OR
✅ On Thursdays
Both correct versions are common, but they follow different sentence patterns.

Imagine these two sentences:
- Thursdays meeting was cancelled.
- Thursday’s meeting was cancelled.
The first looks incorrect because readers expect a possessive form.
Likewise:

This incorrectly uses an apostrophe for a plural noun.
Correct grammar helps your writing appear polished and trustworthy, especially in business emails, academic writing, and professional documents.
