词义辨析

basic，essential，fundamental，radical，vital

• 这些形容词均有“基本的，基础的”之意。
• basic普通用词，指明确、具体的基础或起点。
• essential语气比basic和fundamental强，强调必不可少，暗含某物如缺少某部分，则失去本质特征的意味。
• fundamental书面用词，不如basic使用广泛，侧重指作为基础、根本的抽象的事物。
• radical着重指事物的根本或其来源。
• vital正式用词，侧重指维持生命、活力必不可少的，或生死攸关的。

词源解说

• ☆ 14世纪晚期进入英语，直接源自晚期拉丁语的radicalis，意为有根的；最初源自古典拉丁语的radix，意为根，根部。
