Grammar refers to the rules regarding the current
standard of correctness in speech and writing. Advances in word processing software have
included grammar-checking features. This page covers two topics:
- A modifier is a word or group of words that describes another word and makes its meaning
more specific. Often modifying phrases add information about "where",
"when", or "how" something is done. A modifier works best when it is
right next to the word it modifies. For example, consider the modifiers in the following
sentence (they are underlined for you):
"The awesome dude rode a wave breaking on the shore."
- The word "awesome" is an adjective (or, a one-word modifier). It sits right
next to the "dude" it modifies. Also, the phrase "breaking on the
shore" tells us where he rode the wave; thus, "breaking on the shore" is a
modifying phrase that must be placed next to the "wave" it modifies.
- Below are some examples of poorly placed modifiers. See if you can identify the

- Obviously twenty-five sofas were not shopping on Saturday. Because Shopping on Saturday
is meant to modify Roger, it should be right next to Roger, as follows:
