penchant
A strong liking or preference for something specific.
A penchant is a strong liking or preference for something particular. If you have a penchant for mystery novels, you don't just enjoy them occasionally: you actively seek them out and choose them over other types of books. If your friend has a penchant for spicy food, she'll always pick the hottest sauce available and light up when someone mentions Thai or Indian cuisine.
The word suggests something more specific than just “liking” things in general. You might like desserts, but if you have a penchant for chocolate cake specifically, that's your go-to choice, your favorite that you return to again and again. A teacher might notice a student's penchant for asking challenging questions, or a coach might observe an athlete's penchant for taking risks during games.
Penchant can describe personality traits or habits too. Someone with a penchant for organization keeps their desk neat and their schedule color-coded. A person with a penchant for adventure always suggests the boldest activity. The word captures those distinctive preferences that make someone uniquely themselves.
