Traps
Traps holds closed decks of things that mislead — not vocabulary you select, but a hazard list you work through once and revisit. In French the hub has one deck so far: Meaning changes with gender, the nouns that are two words sharing a spelling — le tour is a turn, la tour a tower; le voile a veil, la voile a sail. The Study row Meaning-changers reference lists them with both senses side by side; the Practice row drills each form as its own card, the article on the front and the sense of that exact form on the back. The deck brings its own nouns: nothing is selected first, and your level is the only filter. Open it from Self Study → Traps (iPhone, iPad) or the Traps item in the Mac sidebar.
The same nouns also appear in Alternate gender pairs under Nouns, as pairs; here they are drilled sense by sense.
