Unfolding or revelation?

Both words do not quite specify the temporal component of experiencing the thing at different times. I honestly doubt such a word or phrase exists in English; which is why I was curious about other languages too.

Curious what you are naming :D The concept of something "revealing more about itself, every time you experience it" can be described by a few terms, though there isn't a single, universally-accepted word or slang for it in English. Here are a few possibilities:

1. **Layered**: This term is often used to describe something complex and multifaceted. 2. **Multifaceted**: Similar to layered, this term suggests that there are many sides or aspects to something. 3. **Palimpsest**: metaphorically , describe something w layers of meaning

For the concept of "meaning less...." there isn't a specific term that captures this idea precisely, but: 1. **Diminishing returns** 2. **Jaded**: 3. **Familiarity breeds contempt**: proverb but fits the brief 4. **Trite**: something that has become dull due to overuse.

Trite's an interesting one! Initially, I had imagined it being dull due to use by others, and not by one person. When formulating the brief for "meaning less over time", I was thinking of something to describe a work of media in the 90s that I used to think highly of.

I'm still looking for something that specifically includes the temporal aspect in the meaning of the word itself, and not as a qualifier. Polysemous is good though! Overall, I'm not confident that my search will end successfully in English.
