Both words are adverbs that are used to describe the extent or degree to which something is true or happens.

Usage

One key difference between "mainly" and "mostly" lies in their usage. "Mainly" is often used to emphasize the most important aspect or part of something, while "mostly" is used to indicate that something happens for the majority of the time or in most cases. For example, you might say, "I mainly eat vegetables for dinner," to emphasize that vegetables are the primary component of your meal. On the other hand, you might say, "I mostly eat vegetables for dinner," to indicate that vegetables make up the majority of your meals.

Extent

Another difference between "mainly" and "mostly" is in the extent to which they describe something. "Mainly" tends to focus on the most important or significant part of something, while "mostly" describes something that happens for the greater part of the time. For example, if you say, "I mainly work from home," you are emphasizing that working from home is the primary location where you work. On the other hand, if you say, "I mostly work from home," you are indicating that working from home is where you spend the majority of your work time.

Emphasis

When it comes to emphasis, "mainly" and "mostly" can be used to highlight different aspects of a statement. "Mainly" is often used to draw attention to the most important or significant part of something, while "mostly" is used to emphasize that something happens for the majority of the time. For example, if you say, "I mainly read science fiction novels," you are emphasizing that science fiction is the primary genre of books you read. On the other hand, if you say, "I mostly read science fiction novels," you are indicating that science fiction makes up the majority of the books you read.

Frequency

One aspect where "mainly" and "mostly" differ is in terms of frequency. "Mainly" is often used to indicate that something is the most important or significant part of a whole, while "mostly" is used to describe something that happens for the majority of the time. For example, if you say, "I mainly go to the gym on weekdays," you are emphasizing that going to the gym on weekdays is the most important part of your exercise routine. On the other hand, if you say, "I mostly go to the gym on weekdays," you are indicating that going to the gym on weekdays is what you do for the majority of the time.
