Lack of practice, metaphorically NYT crossword clue

The clue “Lack of practice, metaphorically” refers to a common phrase used to describe the effects of not using a particular skill for a while. When someone hasn’t engaged in a specific activity recently—like playing an instrument, speaking a language, or exercising—they often feel a bit off or clumsy when they try it again. This idea is often expressed using a metaphor related to machinery or physical condition.

The answer to this clue is “RUST.” Just as metal rusts from lack of use or exposure to the elements, a person’s skills can metaphorically “rust” when they aren’t practiced regularly. This metaphor captures the idea that without consistent use, our abilities can deteriorate or become less sharp over time.
