inherent指物体本身固有的、不能与该物体分割的某种特性。

essential指决定所属事物存在的关键因素。

requisite, essential, indispensable, necessary

这组词都有“必不可少的，必需的”的意思，其区别是：

requisite正式用词，特指为实现某一目的或得到某种结果而应有的需要，有时可与necessary换用。

essential指对事物本身性质具有决定性的重要性，暗含不可缺少，否则便无法存在。

indispensable语气强，侧重指绝对必要性或不可缺少性。

necessary最常用词，侧重由客观因素决定的某种需要，强调不可避免，但并非绝不可缺少。

vital, essential, basic, fundamental, radical

这组词都有“基本的，基础的”的意思，其区别是：

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。

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。

basic普通用词，指明确、具体的基础或起点。

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。
