Questions & Answers about Il y a deux escales. Laquelle est incluse ?
Why do we use Laquelle here instead of Lequel?
Could I just say Quelle est incluse ? instead of Laquelle?
No. Quel and Quelle mean "which" or "what" and are interrogative adjectives, meaning they usually must be placed directly next to a noun (like Quelle escale). To say "which one" as a standalone pronoun, you must use a form of lequel.
Why does incluse have an -e at the end?
What is the masculine form of incluse?
The masculine form is inclus. Unlike many verbs that simply end in -u in the past participle, inclure is irregular and ends in -us. The feminine form simply adds an -e to make it incluse.
