拓 🔊

网络内容摘要 (Web Content Summary):

• 拓 是一个形声字，从“手”，表示动作，声符是“石”或相关部件，部分异体字用作“摭”。 拓 is a phono-semantic compound character: the "hand" radical (手) indicates action, and the phonetic component is "stone" (石) or its variants. Some variant forms use "摭".

• 本字本义与“手”与“石”相关，最初指“捡拾石块”。后来用于扩展、开辟（如“开拓”）。 The original meaning relates to "hand" and "stone", referring to "picking up stones." Later, its meaning extended to "expand" or "open up," as in “开拓” (to pioneer or open up).

• 文化背景上，"拓" 也常用于“拓印”，即用纸墨在石刻上按压，拓取文字或图案。 Culturally, "拓" is used in "拓印" (rubbing), a technique to take ink impressions from stone inscriptions or relief patterns.

• 常用词有“开拓”（to pioneer）、“拓展”（to expand/extend）、“拓片”（rubbing, as in taking an ink impression）。 Common words include: “开拓” (to pioneer), “拓展” (to expand/extend), and “拓片” (rubbing, i.e., ink impressions from inscriptions).

• 易混淆点："拓" 有时与“扩”（扩展）混用，但“拓”偏重于开辟新的领域，“扩”偏重已有范围的扩大。 Easily confused: "拓" is sometimes confused with “扩” (to extend/enlarge), but "拓" emphasizes opening up new areas, while “扩” focuses on enlarging existing ones.
