Student or Learner
Could someone please explain the grammar of the following sentence -
"All he does is speak English".
Is "All he does" the subject, "is" the be verb, "speak" a verb and "English" the noun?
I'm confused with "is speak". Is it ok to have verb + verb?
In fact "does is speak" is verb + verb + verb.
I only studied "to speak" like in "I want to learn to speak English" so "is speak" seems strange.
A break down of the subject/object/verb in the sentence and any explanation would be good.
"All he does (noun clause, subject) is (verb) speak English (subject complement)".
Thanks for your help.
As I understand it -
All he does = noun clause (subject)
is = be verb
speak = linking verb
English = noun (predicate nominative/subject complement)
Is that correct?
