Final answer:
In French, 'le' and 'les', ambiguity is clarified by the context, previous nouns, and the use of subject personal pronouns and object personal pronouns.
Step-by-step explanation:
To clarify to whom the pronouns 'le' and 'les' refer to in French, context and prior mentioned subjects are often used. For instance, if the conversation or text had previously made reference to a specific noun, 'le' or 'les' would be referring back to that noun. Subject personal pronouns (I, you, he, she, it, we, they) and object personal pronouns (me, you, him, her, it, us, them) can also be used to clarify the reference. It's key to understand the different uses of these pronouns and how they relate back to their antecedents in sentences.
