People sometimes confuse sly with simply being secretive. Secretive means keeping things hidden, while sly adds the element of craft or cleverness. Another mistake is treating sly as purely negative. It can be playful, admiring, or neutral depending on context.
Some assume sly equals malicious deceit. Not always. A sly plan might be harmless cleverness, like surprising a friend with cake. Tone and intent matter.
