Prepositions: 08

The Preposition

Recognize a preposition when you see one.

Prepositions are the words that indicate location. Usually, prepositions show this location in the physical world. Check out the three examples below:

The puppy is on the floor.

The puppy is in the trashcan.

The puppy is beside the phone.

On, in, and beside are all prepositions. They are showing where the puppy is. Prepositions can also show location in time. Read the next three examples:

At midnight, Jill craved mashed potatoes with grape jelly.

In the spring, I always vow to plant tomatoes but end up buying them at the supermarket.

During the marathon, Iggy's legs complained with sharp pains shooting up his thighs.

At midnight, in the spring, and during the marathon all show location in time.
Because there are so many possible locations, there are quite a few prepositions. Below is the complete list.

about above according to across after against along along with among apart from around as as for at because of before behind below beneath beside between beyond but* by by means of

concerning despite down during except except for excepting for from in in addition to in back of in case of in front of in place of inside in spite of instead of into like near next of off on

onto on top of out out of outside over past regarding round since through throughout till to toward under underneath unlike until up upon up to with within without

* But is very seldom a preposition. When it is used as a preposition, but means the same as except—Everyone ate frog legs but Jamie. But usually functions as a coordinating conjunction.

Understand how to form a prepositional phrase.

Prepositions generally introduce prepositional phrases. Prepositional phrases look like this:

preposition + optional modifiers + noun, pronoun, or gerund

Here are some examples:

At school

At = preposition; school = noun.

According to us

According to = preposition; us = pronoun.

By chewing

By = preposition; chewing = gerund.

Under the stove

Under = preposition; the = modifier; stove = noun.

In the crumb-filled, rumpled sheets

In = preposition; the, crumb-filled, rumpled = modifiers; sheets = noun.

Realize that some prepositions also function as subordinate conjunctions.

Some prepositions also function as subordinate conjunctions. These prepositions are after, as, before, since, and until. A subordinate conjunction will have both a subject and a verb following it, forming a subordinate clause.
Look at these examples:

After Sam and Esmerelda kissed goodnight

After = subordinate conjunction; Sam, Esmerelda = subjects; kissed = verb.

As Jerome buckled on the parachute

As = subordinate conjunction; Jerome = subject; buckled = verb.

Before I eat these frog legs

Before = subordinate conjunction; I = subject; eat = verb.

Since we have enjoyed the squid eyeball stew

Since = subordinate conjunction; we = subject; have enjoyed = verb.

Until your hiccups stop

Until = subordinate conjunction; hiccups = subject; stop = verb.

If you find a noun [with or without modifiers] following one of these five prepositions, then all you have is a prepositional phrase. Look at these examples:

After the killer calculus test

After = preposition; the, killer, calculus = modifiers; test = noun.

As a good parent

As = preposition; a, good = modifiers; parent = noun.

Before dinner

Before = preposition; dinner = noun.

Since the breakup

Since = preposition; the = modifier; breakup = noun.

Until midnight

Until = preposition; midnight = noun.
