Notes
GENERAL INFO
Dernier means "last" or "final." It is an adjective and agrees in gender and number (e.g., *dernière*, *derniers*, *dernières*).
USAGE
Placed *before* a noun, it typically means "the last one" in a series (e.g., *le dernier chapitre* - the final chapter).
Placed *after* a noun, it means "the previous one" or "the one just before now" (e.g., *le mois dernier* - last month).
TRAPS
Its position is crucial! *La semaine dernière* (last week) refers to the week that just passed. *La dernière semaine* (the last week) refers to the concluding week of a specific event or period.
