| Consider these examples: 
clausecows eat grass This example is a clause, because it contains the
subject "cows" and the predicate "eat
grass." 
phrasecows eating grass What about "cows eating grass"?  This noun phrase
could be a subject, but it has no predicate
attached to it: the adjective phrase "eating grass"
show which cows the writer is referring to, but there is
nothing here to show why the writer is mentioning cows in the first
place. 
clausecows eating grass are visible from the highway This is a complete clause again.  The
subject "cows eating grass" and the
predicate "are visible from the highway" make up a
complete thought. 
clauseRun! This single-word command is also a clause, even though
it does seem to have a subject.  With a direct
command, it is not necessary to include the subject, since it
is obviously the person or people you are talking to: in other words,
the clause really reads "[You] run!".  You should
not usually use direct commands in your essays, except in
quotations. |
