French Relative Pronouns: dont, lequel, où — Complex Forms Explained

Relative pronouns link a dependent clause to its antecedent noun, allowing you to add descriptive details. Beyond the basics (qui, que), advanced relative pronouns like dont (whose/of which), lequel (which one), and où (where) require careful attention to agreement, prepositions, and case.

Short answer

Complex relative pronouns in French include dont (whose, of which, about which) for possession/relationships, lequel/laquelle/lesquels/lesquelles (which) agreeing with the noun, and où (where) for location — each requires specific antecedent context and preposition handling.
