1. In the evening, Sonya will meet one of her friends.
2. In the evenings, Sonya will meet one of her friends.

Thank you for your help. What is the difference between them. Does #1 mean "She will meet her friend this evening (once)." Does #2 mean "She will meet her friend every evening?
Your interpretations are right. You should know, though, that 2 is almost never used.
Yes, you are correct. There is a difference in meaning between the two sentences.
In #1, "In the evening, Sonya will meet one of her friends," it means that Sonya will meet one of her friends specifically in the evening of a particular day. This sentence suggests that the meeting is a one-time occurrence and is not a regular or recurring event.
In #2, "In the evenings, Sonya will meet one of her friends," it implies that Sonya will meet one of her friends on multiple evenings, indicating a regular or recurring event. This sentence suggests that the meeting happens repeatedly, possibly on different evenings or on a daily or weekly basis.
So, to summarize, #1 implies a single meeting in the evening of a specific day, while #2 implies multiple meetings in the evenings on a regular basis.
