In English there are 8 parts of speech or ways words perform in a sentence.
These are:
Let us discuss each one separately.Types of Nouns
(But Christianity, though it is an abstract noun, is also a proper noun and is capitalized.)
GENDER, though rarely used in English, refers to the "attribute" of the noun (or pronoun). That attribute can be Masculine, Feminine or Neuter.
NUMBER is whether the noun is singular (1 and only 1) or plural (more than one). Most nouns have a singular and a plural form. Some nouns (not very many) have only singular or only plural forms.
CASE means that the noun (though usually a pronoun) may some times change form depending upon its function in the sentence. The function of a word in a sentence (subject, object etc.) is determined by the position it has in the sentence. (Each word has a physical location in a sentence. This is called its position.)
There are 4 noun CASES. To decline a noun is to state all its forms in its various cases and numbers (singular and plural).
The noun cases are:
Genitive: This case is used to indicate possession or ownership. Example: "Bill's hat is red." The 's is the genitive case. To be exact it should read as "The hat of Bill. .". However this is an awkward construction and is not used too often.
Dative: This case is used when the noun is the indirect object of the sentence. Example: "Bill's hat fell from the shelf to the floor." In this sentence "the shelf" is the indirect object of the sentence and would be in the dative case.
Accusative: This case is used when the noun is the direct object of the sentence. Example: "Bill's hat fell from the shelf to the floor." Here, "the floor" is the direct object of the sentence and would take the accusative case.
Pronoun declensions:
First Person Second Person Third Person
Sing. Plural Sing. and Plural Singular Plural
NOMINATIVE I we you he, she, it they
GENITIVE mine our(ours) your(yours)2 his, hers, its their(theirs)2
DATIVE me us you her, him, it them
ACCUSATIVE me us you her, him, it them
Interrogative Pronouns: These words indicate questions.
Who, what, when, where, why and how.
When referring to people an unknown noun (or pronoun) usually takes the masculine gender.
Example: The chairman took his position at the desk.
In this example his is a pronoun (in the masculine gender) which refers to the chairman.
Note: Currently there are attempts to "de-sex" English word usage. Though personally I do not agree with these attempts the "de-sexing" can be accomplished in other ways. The use of the term chairwoman or chairperson are acceptable variants. To "de-sex" the situation, the sentence could be written as: "The chairperson took its position at the desk. However in English it is not used for persons only for things or animals. I would suggest using: "The chairperson took a position at the desk." A little change in meaning but it does "de-sex" the situation.
Most inanimate nouns such as boats and buildings take a feminine pronoun.
An adjective must agree with the noun it modifies in gender, number and case. This means that if a noun is masculine the adjective must be masculine. If the noun is plural the adjective that modifies the noun must also be plural. If the noun is in the nominative case the adjective must be in the nominative case.
In usage, some words are primarily used for men and some are primarily used for women. Example: pretty for women and handsome for men. (Though I guess very few would notice the contradiction I would never refer to a man as hysterical.)
Adjectives have an attribute which is used to give additional information to or about the noun which it modifies. This is called form.
The form of an adjective has 3 categories. These are positive, comparative and superlative. Form is used when assigning quality to a noun as measured against something else.
Example: Mary is pretty. (Pretty is the positive form.)
Mary is the prettiest of all the women in the room.
(Prettiest is the superlative form. The superlative form is used when comparing three or more.)
Example: Mary is beautiful.
Of all the women in the room, Mary is the most beautiful.
Types of Verbs
Infinitive: This is the "raw" form of the verb with out any conjugations. "I like to sing."
Transitive: Requires an object to complete its meaning. They can also be changed from active to passive voice.
Some verbs can be transitive in one sentence and intransitive in another.
Intransitive: She reads well. [No object.]
[Want is in the indicative mood.]
[Kiss is in the imperative mood.]
Voice is used to indicate whether the subject of the sentence causes or receives the action of the verb.
Active Voice: A verb having a direct object is active. The subject of an active verb acts.
[Mary is the direct object.]
Tense indicates the time sequence of the verb. Verbs are conjugated (or inflected). To conjugate a verb is to use it in its proper tense, voice, mood, person and number.
The tenses of verbs are:
Present: Action occurring at the present time. I am here.
Past: Action in the immediate past. I was here.
Future: Action which will happen. I will be here
Present Perfect: Action in present tense which is already past
Present participle: I am running.
Past participle: I was running.
Future participle: I will be running.
Present perfect participle: I have been running.
Past perfect participle: I had been running.
Future perfect participle: I will have been running.
Second person: The verb action is directed to a specific person.
Adverbs can often be formed from adjectives by adding -ly to an adjective. Adverbs can also have forms of comparison similar to adjectives.
Barbara sings more quietly than does Helen.
Nancy sings most quietly of all.
Types of articles.
Indefinite: Used to indicate a not specific general noun or nouns. a bird, an apple. A and an are the indefinite articles. (If the next word starts with a vowel use an.)
Definite: Used to indicate a specific noun or nouns. the book, the store.

Nouns have gender, number and case. Pronouns have person, gender, number and case.
Adjectives have gender number and case. Adjectives must agree with the noun they modify in gender, number and case.
Verbs have mood, voice and tense as well as person and number. A verb must agree with its subject in person and number.
Though this is a very brief treatment of English grammar this will meet a very large portion of your needs.
