Questions & Answers about Por un lado, el tren es ecológico; en cambio, el carro contamina mucho.
The lesson mentions por un lado ... por otro lado, but this sentence uses en cambio. Why?
Is carro the standard word for car?
In most of Latin America, carro or auto is the standard word for car. If you previously studied Spanish from Spain, you might be more used to hearing coche, but carro is perfectly natural and expected for Latin American speakers.
Why does the sentence use the verb contamina (pollutes) instead of an adjective to match ecológico?
Spanish often prefers using active verbs where English might use a descriptive adjective. While you could technically say es muy contaminante (is very polluting) to match the structure of the first half, it sounds much more natural and direct in Spanish to just say contamina mucho (it pollutes a lot).
Why is there a semicolon before en cambio and a comma after it?
When connecting two complete, independent phrases with a contrastive linker like en cambio, Spanish punctuation rules generally use a semicolon right before the linker and a comma right after it. It works just like the English word however!
