_A_ points out _man_, and _who is wise_ tells the _kind_ of man. _A man who
is wise_ is the modified subject; the predicate is unmodified. _Who_ is the
subject of the dependent clause, _is_ is the predicate, and _wise_ is the
attribute complement. _Who_ connects the two clauses.

1. He that runs may read.
2. Man is the only animal that laughs and weeps.

4. He necessarily remains weak who never tries exertion.
5. The meridians are those lines that extend from pole to pole.
6. He who will not be ruled by the rudder must be ruled by the rock.
7. Animals that have a backbone are called vertebrates.

9. The thick mists which prevail in the neighborhood of Newfoundland are
caused by the warm waters of the Gulf Stream.
10. The power which brings a pin to the ground holds the earth in its
orbit.
11. Death is the black camel which kneels at every man's gate.
12. Our best friends are they who tell us of our faults, and help us to
mend them.

The pupil will notice that, in some of these sentences, the dependent
clause modifies the subject, and that, in others, it modifies the noun
complement.

+COMMA--RULE.--The _adjective_ or the _adverb clause_, when it does not
closely follow and restrict the word modified, is generally set off by the
comma+.
