الأشهر
"The months."
In this sentence, "الأشهر" means "months" in the context where it is used to describe a collection of time periods (months of beauty).
الشهر القادم سيكون من الأشهر الجميلة.
The coming month will be one of the most beautiful months.
Here, "الأشهر" means "most famous," describing the popularity of the summer season.

The most famous in this country is the summer season because of the mild weather.
In this context, "الأشهر" again means "most famous," but it is used to describe individuals instead of a season or concept.
