Is a limit order a maker fee?

Excuse me, could you please clarify for me if a limit order is automatically considered a maker fee in the world of cryptocurrency trading? I've heard that market orders often attract taker fees, but I'm unsure about the distinction when it comes to limit orders and whether they're classified as maker or taker transactions. Could you elaborate on this, and perhaps explain the reasoning behind such categorization? Thank you in advance for your insight.
