名 词: essentiality
副 词: essentially
近义词:
[n.] thing

反义词:
[n.] inessential, nonessential
[n.] unnecessary, unneeded, inessential, unessential, unimportant, expendable
解析:
basic: 普通用词,指明确、基础或起点。
essential: 语气比basic和fundamental强,强调不可少,暗含某如缺少某部分,则失去本质特征意味。
fundamental: 书面用词,不如basic使用广泛,侧重指作为基础、根本抽象
radical: 着重指事根本或其来源。
vital: 正式用词,侧重指维持生命、活力不可少,或生死攸关
