Final answer:
The pronoun 'en' replaces nouns preceded by the partitive articles 'du', 'de la', and 'des' in French.
Step-by-step explanation:
In French, the pronoun 'en' replaces nouns that are preceded by the partitive articles 'du', 'de la', and 'des.'
For example:
- J'ai acheté du pain. - I bought some bread.
- J'en ai acheté. - I bought some (of it).
Here, 'en' replaces 'du pain' to avoid repeating the noun.
