请分析一下这句话的主谓宾,What the Englishman showed to the waiter was not enough to make the waiter understand him correctly.

主What the Englishman showed to the waiter 那位英国人给服务生看的
谓was not
宾enough to make the waiter understand him correctly. 足以使服务生正确地理解他
那位英国人给服务生看的东西并不足以让对方准确地明白他的意思。

这个英国人给这个服务员所出示的(东西)没有足够能够使服务员完全明白

主语：What the Englishman showed to the waiter
谓语：was not
没宾语，有表语：enough to make the waiter understand him correctly
这个英国人向服务员说明的不足以让服务员正确明白他的意思。

主语从句 what the englishman showed to the waiter 是主语 + is 系动词 not + enough 表语 + to make the waiter understand him correctly 不定式引导的动词结构 表目的 语法上是状语成分

句子的主干是：
What was not enough to do sth.
“什么”不足以让某人做某事.
What the Englishman showed to the waiter是主语从句,英国人向服务员所描述的东西；
make the waiter understand him correctly.是“make sb.do sth.”让某人做某事,
让服务员很好地理解.
