A thesis statement is a short passage -- usually only a single sentence -- summarising the fundamental argument of an essay or report. Typically, the thesis statement will appear near the end of your introductory paragraph.

The basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. For example, in the word "unflattering," the root is simply "flatter," while the prefix "un-" makes the word negative, and the suffix "-ing" changes it from a verb into an adjective (specifically, a participle).

English itself does not use prefixes as heavily as it once did, but many English words come from Latin, which uses prefixes and suffixes (you can use the word affix to refer either to a prefix or a suffix) quite extensively. For example, the words "prefix," "suffix," and "affix" themselves are all formed from "fix" by the use of prefixes:

• "ad" (to) + "fix" (attached) = "affix"
• "pre" (before) + "fix" = "prefix"
• "sub" (under) + "fix" = "suffix"

Note that both the "-d" of "ad" and the "-b" of "sub" change the last letter.

Here are some of the most common Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary):

ab

(away) abrupt, absent, absolve

ad

(to) adverb, advertisment, afflict

in

(not) incapable, indecisive, intolerable

inter

(between, among) intercept, interdependent, interprovincial

intra

(within) intramural, intrapersonal, intraprovincial

pre

(before) prefabricate, preface prefer

post

(after) postpone, postscript, postwar

sub

(under) submarine, subscription, suspect

trans

(across) transfer, transit, translate

When two words, clauses, or phrases stand close together and share the same part of the sentence, they are in apposition and are called appositives.

In fact, an appositive is very much like a subject complement, only without the linking verb:

subject complement

My brother is a research associate.

appositive

My brother the research associate works at a large polling firm.

subject complement

Jean became a magistrate.

appositive

I have never met Jean the magistrate.

In addition to their various classifications, nouns pronouns have three major characteristics: case, number, and gender.

Noun and Pronoun Case

The case of a noun or pronoun determines how you can use it in a phrase or clause. There are three cases in Modern English (as opposed to eight in Classical Latin, four in German, and only two in French):

Subject

You use the subject case for a noun or pronoun which stands alone, is the subject of a clause, is the subject complement, or stands in apposition to any of these.

Object

You use the object case for the object of a preposition, a verb, or a verbal, or for any noun or pronoun which stands in apposition to one of these.

Possessive

You use the possessive case for any noun or pronoun which acts an an adjective, implicitly or explicitly modifying another element in the sentence.

Nouns always take the same form in the subject case and the object case, while pronouns often change their form. Both nouns and pronouns usually change their form for the possessive case:

Subject Case

The man travelled to Newfoundland.

He travelled to Newfoundland.

Object Case

The taxi drove the man to the airport.

The taxi drove him to the airport.

Possessive Case

The baggage handlers lost the man's suitcase.

The baggage handlers lost his suitcase.

For further information, see possessive nouns, possessive pronouns, and possessive adjectives.

Noun and Pronoun Number

The number of a noun or pronoun is either singular, if it refers to one thing, or plural, if it refers to more than one thing (if the noun or pronoun is the subject, then its number will also affect the verb). Note the difference in number in the following examples:

Singular

That woman is concerned about this issue.

She is concerned about this issue.

Plural

Those women are concerned about this issue.

They are concerned about this issue.

It is important to note that the pronoun "they" is in the processing of becoming singular as well as plural. For example, one might say

A person called and they did not leave their name.

This construction allows the speaker to avoid identifying the gender of a person, and it has been common in speech for decades, if not for centuries. Be aware, however, that some people still consider it unacceptable for formal writing.

For more information, see noun plurals.

Noun and Pronoun Gender

Unlike the Romance languages (such as French, Spanish, and Italian), English has three genders for nouns and pronouns: masculine, feminine, and neuter.

Generally, the English language uses natural gender rather than grammatical gender -- that is, the gender of a word is usually based on its biology (so there is little need to remember whether a word is masculine or feminine). A noun that refers to something with male sexual organs is masculine, a noun that refers to something with female sexual organs is feminine and most other nouns are neuter by default.

There was a time when you could use the masculine gender by default when you did not know a person's natural gender, but very few people accept this usage any longer.

There are, moreover, a few tricky points. First, you may refer to all animals in the neuter gender, or you may refer to them by their natural gender:

Neuter

What a beautiful dog! Does it bite?

Natural Gender

What a beautiful dog! Does she bite?

Second, You usually assign mythical beings (such as gods) to a natural gender, even if you do not believe that the beings have actual sexual organs:

God is great. God is good. Let us thank her for our food.

Finally, people sometimes assign natural gender to inanimate objects, especially if they live or work closely with them. When engineers were mostly men, for example, they tended to refer to large machines in the feminine:

She is a fine ship.

For more information, see the discussion of gender-specific nouns.

Noun and Pronoun Person

Personal pronouns always belong to one of three persons: first person if they refer to the speaker or writer (or to a group including the speaker or writer), second person if they refer to the audience of the speaker or writer (or to a group including the audience), and third person if they refer to anyone else (if the noun or pronoun is the subject, then its person will also affect the verb). Nouns and other types of pronouns are always in the third person. Note the differences in person in the following examples:

First Person

I will come tomorrow.

Bob showed the budget to us.

Second Person

You should not forget to vote.

Where is your coat?

Third Person

It arrived yesterday.

How can you stand working with them?

Traditionally, you were required to use the third person in formal academic writing, but some people now accept the first person. Whichever you choose, however, you must be consistent.
