扩展

• 拼音: kuò zhǎn
• 汉字拆解: 扩 = 扌(hand radical) + 广 (phonetic component); 展 = 尸 (body radical) + 共 (phonetic component, spreading)

含义

To expand; to extend; to broaden. Refers to stretching something outward in reach, scope, or capacity.

扩展 is similar to 扩大 but often implies spreading outward or extending in reach rather than simply growing in size. It is commonly used in technology contexts (expanding a network, expanding storage), as well as for extending skills, territory, or market reach.
