✦Grammar Breakdown
DerHerbstfängtimSeptemberan.
Definite article (Der)
‘Der’ is the masculine nominative singular article, matching ‘Herbst’ which is a masculine noun.
Noun gender (Herbst)
‘Herbst’ is masculine; its plural is ‘Herbste’ and the genitive is ‘des Herbstes’.
Separable verb (anfangen)
‘anfangen’ splits in main clause: the stem ‘fängt’ stays in the verb position, the prefix ‘an’ moves to the sentence end.
Preposition + article (im)
‘im’ = ‘in dem’, a contraction of the dative preposition ‘in’ with the definite article ‘dem’. It requires the following noun to be in dative case.
Month in dative (September)
Months used with ‘im’ are in dative, so ‘September’ stays unchanged because month names have no distinct dative ending.

It also aligns with cultural events like Oktoberfest, which marks the height of the season.
