"You eat the hot apple."
Translation:Tu manges la pomme chaude.
I know it's too late to reply and you probably don't use Duolingo anymore. But I also want to help others who may have same problem. Most of them go after , but some short ones or the ones French use a lot go before, like joli/grand... .etc. Practice more or talk more to a French and you will know it.
in french or in Spanish as I know the adjective will always go after the noun, like the apple red, its all the way around, but for me that im Spanish, English is all the way around, so really u juts have to turn things around.
