Mostly vs. Mainly: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 20, 2023
Mostly means largely, for the most part. Mainly means primarily, chiefly.

Key Differences
Mostly is often used to indicate that something is true or applies to the majority of situations, people, or things, but not all. Mainly, on the other hand, suggests that one particular thing is primarily responsible or significant among others. They both imply a degree of exclusivity, but mostly leans towards quantifiable aspects while mainly hints at qualitative importance.

In usage, mostly is apt for instances where there's a notable but not absolute dominance. For example, "The crowd was mostly teenagers." It suggests a large part but not entirety. Mainly tends to underscore the primary cause, reason, or factor, as in, "The event was mainly for charity." It emphasizes the chief purpose or element.

When we talk about proportion, mostly is your word. It fits well when you're quantifying: "The class is mostly international students." Here, it implies a high percentage. Conversely, mainly is best for emphasizing the principal element: "The discussion was mainly about politics," where politics is the core subject.

Mostly also has a flavor of generalization, suitable for broad strokes: "She's mostly quiet in meetings." It doesn’t exclude exceptions. Mainly leans towards specificity, highlighting the primary aspect: "He’s mainly interested in jazz," focusing on jazz as the key interest.

In some contexts, both words can be interchangeable without much change in meaning. For instance, "The participants were mostly/mainly women." However, the nuance remains, with mostly indicating a high number and mainly underscoring women as the primary group.
