mai
"Mai" in German means "May," the fifth month of the year.
The word 'Mai' is used here as a proper noun, indicating the month of May in the year.
Im Mai blühen viele Blumen.
In May, many flowers bloom.
Here, 'Mai' signifies a symbolic phrase, using the month of May as a metaphor for a time of joy and prosperity.
Das ist ein Mai des Glücks.
This is a May of happiness.
In this case, 'Mai' functions as a proper noun again, but instead of being the name of a month, it is the personal name of an individual.
