In modern usage, it also refers to a Personal Identification Number (PIN) for security in banking and digital systems.
Historically, pins date back to ancient times for practical purposes. The word derives from Old English 'pinn', meaning a peg or bolt. As a verb, 'to pin' involves attaching or restricting something physically or metaphorically.
Common contexts include sewing, electronics (e.g., microchip pins), and figurative expressions like 'pinning hopes'. Derivatives like 'pinless' adapt the concept to new technologies.扩展阅读Cambridge Dictionary: pinhttps://dictionary.cambridge.org/dictionary/english/pinMerriam-Webster: pinhttps://www.merriam-webster.com/dictionary/pinWikipedia: Pin (disambiguation)https://en.wikipedia.org/wiki/Pin词典内容由 AI 生成质量反馈绿色版权© 2025 萌翻-京公网安备11011502038737号 -京ICP备2025123831号-1
