For a fastening device that tightens an object or part of a garment (as in fastening a belt)
For a term indicating completion or termination: "He went on with his work, leaving me to buckle away."
As a verb: "She made it as though she were buckling down for a fight." The word "buckle" has been used across different fields and contexts. In engineering terms, the phrase is used in construction engineering to describe a fastening mechanism that tightens a bolt or screw onto a member of a structure (as in tightening a nut and bolt). In computer science, it's used in a similar context: It refers to an external device used by a software program or application to connect with other systems or devices. In literature, the phrase is often used to describe a character's emotional state or behavior. In music, "buckle" can mean something like "to hold in place" and is used in various contexts such as:
When someone is feeling comfortable or relaxed; "I'm sure he'll be able to carry on with his work, the way he always does."
A metaphor for a character who is being very unresponsive or passive, like they're just going along without thinking about it: "It was a little bit of a buck," she said. "But I think that's what you'd expect from someone who hasn't had their mind blown." Overall, the word "buckle" has evolved to have many different meanings and is used in a wide range of contexts, from everyday life to academic study.
