Here are some ways "subtle" is used:
1. Delicate or understated: This is the most common meaning. It describes something that is hard to perceive, like a soft color or a quiet whisper.
* Example: "The artist used subtle brushstrokes to create a sense of depth."
2. Not directly stated, but implied: This meaning refers to something that is hinted at indirectly, rather than explicitly mentioned.
* Example: "There was a subtle shift in the mood of the room after she left."
3. Difficult to understand or analyze: This meaning relates to something that is complex and requires careful attention to be grasped.
* Example: "The novel explores subtle themes of identity and belonging."
4. Skillful and cunning: In this context, "subtle" refers to someone who is very good at manipulating situations or people without being obvious.
* Example: "He was a subtle negotiator, always able to get what he wanted."
In general, "subtle" implies something that is refined, delicate, and nuanced. It is the opposite of obvious, blatant, or crude.
