parsing

[tkacka15]

All you can do is give your all.

All you can do (a subordinate clause) - a subject of the sentence where you is a subject, can do a predicator and All (a noun) an object;

is - a predicator of the sentence (linking verb);

give your all (a non-finite subordinate clause) a complement of the sentence where give is a predicator and your all (a noun phrase in which the noun all is the head of the phrase and the possessive adjective your a modifier) an object.

Is my parsing acceptable?

Thank you.

Thank you, Piscean, for your reply. Indeed, '(...that) you can do' is the subordinate clause.

Do you agree with me that '(...that) you can do' is a relative clause modifying the noun All in the noun phrase All you can do which is the subject of the sentence All you can do is give your all?
