What is the grammatical name given to, and the function of, the part of the sentence below in bold?
Maneuvring a tanker is likewise a daunting challenge.
As Gary's Student has pointed out, in the simplified example
the subject of the sentence is maneuvering the tanker;
in order to be a subject, this must be a noun. But it doesn't look like a noun.
It looks exactly like a verb phrase, with a verb maneuvering
and a direct object noun phrase the tanker.
And that's what it is. A verb phrase, acting as a noun phrase. But not just any old verb phrase.
Maneuvering the tanker is a Gerund verb phrase -- that's what the -ing suffix marks.
This verb phrase is all that's left of the subject gerund complement clause
Indef
's maneuvering the tanker is a challenge for Indef
after removing all the references to the indefinite subject
("Indef
", the person who's doing the maneuvering and experiencing the challenge).
This has the effect of making the clause generic, true for any agent subject.
So, to answer your question about grammatical name and function:
These are all true, simultaneously, depending on which aspect of the sentence you're talking about.
Note:
- that a clause is any constituent with a subject and a verb
(though the subject may only be implied in context, as here),
- that a verb phrase is just a clause with a missing subject,
- that a clause can be the subject or the object of a verb
(and therefore a clause can itself be the subject, or object, of another clause), and
- that a noun phrase is anything that behaves like a noun in a clause.
