noun
particular interest; fondness; personal taste
Refers to a personal liking or inclination toward something, often used in contexts like hobbies, preferences, or subjective appeal. Not as common as 趣味 alone; the 性 suffix adds a nuance of 'nature' or 'quality'.
彼の趣味性が強く出た部屋の飾り付けだ。
The room's decoration strongly reflects his personal taste.
