Prepositions

Prepositions form a closed class

There is a restricted number of prepositions and it is difficult to add new members. Accordingly, like auxiliary verbsnumerals, determiners, pronouns and conjunctions, prepositions form a closed class of words.

Prepositions are relation words

Prepositions function as relation words that connect elements of an utterance together. Predominantly, they relate a noun phrase to another unit in the utterance. Consider the following.

the cat is on the mat

Here, the preposition on relates the noun phrase the cat to another unit in the utterance, the mat. Specifically, it signifies a relationship of place, i.e. the cat is on the mat. Other examples of prepositions signaling place include:

the car is in the garage

the boy is beside the fence

the wreck is beneath the waves

Anna is standing next to Dan’s camera

As well as expressing a relationship of place, prepositions can also express relationships of time and logic, e.g.

time:

they left after the meal

he cried during the funeral

Carl was drunk before the wedding

logic:

we’re upset because of his behavior

we won due to his skill

we knew from his own admission

Expressing several relationships

The use of from in the last example above was interpretable as expressing a relationship of logic. However, it is possible for prepositions to express more than one relationship (of place, time or logic). Consider the use of from in the following:

they came from her office [place]

let’s start from the beginning [time]

we knew from her actions [logic]

Linking verbs and adjectives to objects

Another function of prepositions is to link a prepositional phrase via a verb or adjective to the Object of an utterance. A prepositional phrase is a phrase made up of a preposition and a noun phrase, e.g.

prepositional phrase

preposition

noun phrase

at

four o’ clock

on

the wall

with

their three friends

Linking verbs

verb

prepositional phrase

Rutger

he

with his friends

Karen

Linking adjectives

Finally, prepositions may also connect to an adjective:

adjective

prepositional phrase

Anila was

for the meeting

her touch is

soft

on his skin

Jeff can be

cruel

with her
