So, without further ado, let’s get started!
What Is The Meaning Of “Semi Weekly”?

Before diving into which one to use, you need to know the specific meaning of both the terms— “Semiweekly” and “Biweekly”.
Definition
The word “Semiweekly” refers to something happening twice a week. Since ‘semi’ means literally the ‘half’ of something, the term divides the week into two parts.
Moreover, this term is generally used to refer to something happening once every half of the week. So, by adding it up, it becomes twice a week.
When To Use “Semi-Weekly”?
The term “Semiweekly” is usually used when you want to explain how many times something occurs in a week.
So, when something is happening two times within a week, you can use the term “Semiweekly” to describe it.
Furthermore, you can use this term both as an adjective as well as an adverb in your sentences.
- Adjective: As an adjective, it is used to describe something (noun) that is happening twice a week.
