延伸
How to Understand
延伸 means 'extension' or 'expansion,' often referring to the act of extending something physically or metaphorically. It can describe a continuation or development of an idea, a line, or a concept.
The character 延 (yán) originally meant 'to stretch' or 'to prolong,' while 伸 (shēn) means 'to extend' or 'to stretch out.' Together, they form a compound that conveys the idea of lengthening or expanding something in space or time.
延伸 is commonly used in contexts such as architecture, design, and abstract thinking. For example, it might refer to the extension of a road, the expansion of a business, or the development of an argument. It is also used in technical fields like engineering and computer science to describe the expansion of systems or processes.
