Er (Pronoun)
Third‑person singular personal pronoun in the nominative case, used as the subject of the sentence.
ist (Auxiliary ‘sein’)
In the Perfekt tense, motion verbs like kommen take ‘sein’ as the auxiliary; here it is conjugated in the present tense (3rd person singular).
bei (Preposition)
‘bei’ means ‘at’ or ‘by’ and governs the dative case. With time expressions it signals the moment something happens.
Sonnenaufgang (Noun, dative)
Masculine noun meaning ‘sunrise’. After ‘bei’ it stays in the dative singular (no article needed in this idiom).
gekommen (Past Participle)
Past participle of kommen, used together with ‘sein’ to form the Perfekt of motion verbs.

✕Common Mistakes
Er hat bei Sonnenaufgang gekommen.
Motion verbs use ‘sein’ as the auxiliary, not ‘haben’.
Er ist bei den Sonnenaufgang gekommen.
‘bei’ requires dative; the noun ‘Sonnenaufgang’ is used without an article in this idiom.
Er ist am Sonnenaufgang gekommen.
‘am’ (an dem) is used with clock times; for sunrise the idiomatic preposition is ‘bei’.
↔Alternatives
Er kam bei Sonnenaufgang an.
He arrived at sunrise.
Er ist zum Sonnenaufgang gekommen.
He came at sunrise.
Er kam zur Morgendämmerung.
He came at dawn.
Cultural Tip
In German, ‘bei’ is the go‑to preposition for time points that are not exact clock times (e.g., bei Sonnenaufgang, bei Nacht). Unlike English, you don’t need an article before ‘Sonnenaufgang’. Also, motion verbs such as kommen, gehen, fahren always use ‘sein’ as the auxiliary in the Perfekt, which is a frequent stumbling block for learners.
