Kelsey -- please click Post a New Question and ask your question. It's very confusing when someone "piggy-backs" on another's question.

The three statements you provided are slightly different in terms of the number of plans being suggested.

1. "Let's make plans for next month." This statement implies that you want to make more than one plan for the upcoming month. It could mean that you want to make multiple plans throughout the month, such as scheduling various activities or events.

2. "Let's make a plan for next month." This statement suggests that you want to create one specific plan for the next month. It could refer to a single event or activity that you want to organize and prepare for.

3. "Let's make two plans for next month." This statement is more specific and indicates that you want to make exactly two plans for the next month. It implies that you have two particular events or activities in mind that you want to schedule and coordinate.

So, the main difference lies in the number of plans being suggested. The first two statements leave the number of plans unspecified or open-ended, while the third statement specifically mentions making two plans.

Regarding your second question, the word "plan" can refer to a single plan or multiple plans depending on the context. In the statements above, "a plan" indicates one plan, while "plans" or specifying a particular number like "two plans" refers to multiple plans.
