"He talks about the dresses."
Where is the reference in this translation to "the" dresses. "Des robes" translates as "Dresses" not "The dresses." In the context of the verb "parle," the speaker talks "about dresses" but not "the dresses" since "the dresses" needs the definite article. My translation, therefore, was "Il parle des les robes" which apparently is wrong but does include the definite article. Obviously, I don't know the rule, so anyone who can explain is welcome and the help is appreciated.
