Breakdown of Укроп пахнет сильнее, а петрушка выглядит ярче на тарелке.
Questions & Answers about Укроп пахнет сильнее, а петрушка выглядит ярче на тарелке.
А often links two ideas that are being contrasted or compared.
In this sentence, the speaker is setting dill and parsley side by side:
- Укроп пахнет сильнее
- а петрушка выглядит ярче
So а is very natural because it suggests as for parsley / whereas parsley.
A rough sense is:
- Dill smells stronger, whereas parsley looks brighter on the plate.
If you used и, it would sound more like simple addition, with less contrast.
Both are in the nominative case because they are the subjects of the two clauses.
- укроп пахнет = dill smells
- петрушка выглядит = parsley looks/appears
Each noun is doing the action of the verb, so nominative is the expected case.
