Here’s what’s new: the slang meaning of "arch" is typically used to describe someone’s demeanor as playfully mischievous, sly, or knowing in a way that’s a bit superior or wry. It can also describe arch humor or an arch remark—deliberately ironic or teasing. The term can appear in phrases like “arch humor” or “arch opponent” to signal a sly, confident tone.
How it’s being used in conversation
- Arch as an adjective: describes a person or comment that is saucy, impish, or subtly mocking.
- Arch as a noun in slang discussions: sometimes used to label a type of wit or tone rather than a physical arch.
- Arch in titles or prefixes (arch-): in some contexts, indicates superiority or prominence (e.g., arch-enemy, archbishop), but this sense is more formal than slang.
Illustration
- If someone makes an archly witty remark about a situation, they’re delivering a sly, slightly superior joke rather than a straightforward one.
