Questions & Answers about В парке хороший воздух.
Why is the word for park spelled парке here?
It is in the Prepositional case because it follows the preposition в (in) to indicate a location. For most masculine nouns ending in a consonant, like парк, you add -е to make it Prepositional.
Where is the verb in this sentence?
The verb 'is' is omitted in Russian present tense sentences. You literally just say 'In the park good air' and the action of being is simply understood.
Why does the adjective хороший end in -ий instead of the standard masculine ending -ый?
The word воздух (air) is a masculine noun, so it needs a masculine adjective. However, Russian spelling rules state that you can never write the letter ы after the letter ш. Because of this rule, the ending must change from -ый to -ий.
Could I change the word order to воздух хороший?
Yes, but it slightly changes the conversational focus. В парке хороший воздух treats 'good air' as a single idea, translating closest to 'There is good air in the park.' Saying В парке воздух хороший puts the emphasis specifically on the adjective, meaning 'The air in the park is good.'
