kes the noun or pronoun to which it is joined equivalent to an
adjective or an adverb. The expression "John is behind the press" is
equivalent to an adjective describing John. That is, he is "John
behind-the-press." Prepositions are governing words and the words
governed by or depending on them are always in the objective case.

_Conjunctions_

A conjunction is the coupling link between the parts of a train of
thought. It is of no purpose whatever except to connect.

I am cold and hungry and tired and I am going home.

Care should be taken to avoid confusing _and_ and _but_ and _and_ and
_or_.

He sees the right and does the wrong.

should be

He sees the right but does the wrong.

The ideas are contrasted, not associated.

I did not see Thomas and John.

should be

I did not see Thomas or John.

The first phrase means that I did not see them together, it says nothing
about seeing them separately.

_Either_--_or_ and _neither_--_nor_ are called correlative conjunctions.
They should always be paired in this way. _Neither_ should never be
paired with _or_ nor _either_ with _nor_. Each member of the pair
should be placed in the same relative position, that is before the same
part of speech.

I could neither see him nor his father.

is wrong. It should be

I could see neither him nor his father.

This rule applies to all other correlatives, that is since they are
correlatives in form they should be correlatives in position also. It is
correct to say

It belongs both to you and to me.

or

It belongs to both you and me.

but not

It belongs both to you and me.

_Interjections_

An interjection is a word or sound expressing emotion only such as a
shout, a groan, a hiss, a sob, or the like, such as _Oh_, _alas_,
_hush_.

_General Notes_

The position of words in a sentence is often very important.
Misplacement will frequently cause ambiguities and absurdities which
punctuation will not remove. What does the phrase "I only saw him" mean?
A newspaper advertisement describing a certain dog which was offered for
sale says "He is thoroughly house-broken, will eat anything, is very
fond of children." As a rule modifiers should be kept close to the
words, clauses, or phrases which they modify, but due regard should be
given to sense and to ease of expression.

A word or phrase which can be easily supplied from the context
