Learn German: Jeder Passagier genießt die schöne Aussicht. - Every passenger enjoys the beautiful view.

The word for "every" (jeder) changes its ending to match the gender and case of the noun it describes. Since Passagier (passenger) is a masculine noun and is the subject of the sentence (Nominative case), it takes the masculine ending -er.

Why does the adjective schöne end in -e here?

In German, when an adjective comes after a definite article like die, it takes a "weak" ending. Since Aussicht (view) is a feminine noun in the Accusative case (it is the thing being enjoyed), the adjective ending is simply -e.

Is there a trick to knowing that Aussicht is a feminine noun?

Yes! Aussicht is made from aus (out) and Sicht (sight/view). Nouns ending in -t that are derived from verbs (like Sicht from sehen) are almost always feminine.

The verb is genießt. Is the infinitive form spelled with an ß or ss?

The infinitive is genießen (to enjoy), spelled with an ß (Eszett). A helpful spelling rule in German is to use ß after long vowel sounds (like the long "e" sound in "ie") and ss after short vowel sounds.
