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'.

You can feel the creator's personal fondness in this design.
Compound of 趣味 (interest, hobby) and 性 (nature, quality). The exact historical derivation is uncertain, but it follows a common pattern of forming abstract nouns.
