0590 Low-key - English Idioms

Explanation

As an adverb: Done in a subtle, understated, or quiet way; not intended to attract a lot of attention.
As an adjective: Modest, restrained, not intense or extreme.
Can also mean 'secretly' or 'slightly'.

Origin

The term low-key itself isn't new and has existed in English for a long time, often used in technical contexts like lighting or music (low key lighting, low key notes).
Its modern slang usage, particularly the adverbial form meaning 'slightly' or 'secretly', gained significant traction in the 2010s, especially within youth culture, AAVE, and online communities.
It contrasts with high-key (intense, obvious).

Overuse can make speech sound juvenile or non-committal in inappropriate contexts.
