Best practice

Use "a sly grin" to subtly hint at hidden intentions or amusement, rather than stating them directly. This can add depth and intrigue to your writing.

Common error

Avoid using "a sly grin" as a generic descriptor for any type of smile. It specifically denotes a knowing, mischievous, or subtly cunning expression. Using it indiscriminately weakens its impact and may misrepresent the character's emotion.
