The words rely and reliance are closely related in meaning but differ in grammatical function and usage. While both convey the idea of depending on someone or something, they are used in different contexts. Understanding how to use them correctly helps you communicate more effectively, whether you’re writing formally or speaking casually.
Definition of Rely
Rely is a verb. It means to depend on or trust someone or something to do what is needed or expected. When you rely on something, you believe it will support you, help you, or be there when needed.
Examples of Rely in Sentences

In each of these examples, the subject is depending on an object for a specific outcome or benefit.

Examples of Reliance in Sentences

Here, the word reliance emphasizes the overall dependence rather than the act of depending.
Grammatical Roles of Rely and Reliance
The key difference lies in their grammatical use. Rely functions as a verb and often appears with prepositions like “on” or “upon.” On the other hand, reliance is a noun and is often followed by the preposition “on.”
Example:
Verb: Many people rely on public transportation.
Noun: There is a growing reliance on technology in classrooms.
When to Use Rely Instead of Reliance
Use rely when you want to describe the action of depending. It’s more suitable when you are explaining who is depending and what they are depending on, especially in everyday conversation or informal writing.
For example:
I rely on my team to meet the deadline.
You can rely on me to be there.
When to Use Reliance Instead of Rely
Use reliance when you’re discussing the concept of dependence itself. It’s more appropriate in formal writing, analysis, or when you want to focus on the idea rather than the action.
For example:
The article discussed the growing reliance on digital banking.
Reducing reliance on imports can boost the local economy.
