predicate adjective
is separated from the noun or pronoun it modifies by a verb.
Also note that the same word can be used in different capabilities. Some pronouns and nouns can also function as adjectives. Most of the
indefinite pronouns
can also be used as adjectives.
Example: Both girls wanted to go to the dance. (Both as adjective)
Both of you want it? (Both as pronoun)
Here is an example of a noun functioning as an adjective: litter box
In this instance the word litter is being used as an adjective, not a noun.
The Verb
It is commonly known that the verb is the action word. The verb in a sentence can also help to make a statement. The action described may be physical or mental.
Transitive vs Intransitive Verbs
Action verbs may or may not take or refer to an object. Those verbs that are linked to an object are called transitive: example, He finished the poem. Those verbs that can express an action without a noun are called intransitive: example, The writer quit.
Some intransitive verbs help to make the sentence complete by expressing a state or condition. These verbs are linked to the word that it is describing. Therefore, they are called linking verbs. The most common linking verb is the word be and its forms: am, is, are, was, were, be, being, been and phrases that end in a form of be. Other common linking verbs are: appear, grow, seem, stay, become, look, smell, taste, feel, remain and sound.
Helping verbs are also used. These are verbs that help the main verb to express action or make a statement. The common helping verbs are: am, has, can (may) have, are, had, could (would, should) be, is, can, could (would, should) have, was, may, will (shall) have been, were, will (shall) be, might have, do, will (shall) have, might have been, did, has (had) been, must, have, can (may) be, must have and must have been.
The Adverb
The adverb is used to modify a verb, adjective or another adverb. It functions much like an adjective does for a noun. It usually will tell how, when, where or to what extent the action of the verb is done. Some adverbs are used mostly to emphasize. On occasion, nouns will be used adverbially. An example: Lindiana taught us yesterday.
Here the word yesterday is being used as an adverb, not a noun.
The Preposition
The preposition is used to show the relation of a noun or pronoun to some other word within the sentence. Here is an example: She enjoys writing
in
the library more than working
on
her laptop.
In the above sentence, in and on are prepositions. In is used to link the ideas of writing and the library. On is used to link the ideas of working and laptop.
Prepositions always appear in a phrase and are usually located at the beginning.
The noun or pronoun at the end of the phrase is called the object of the preposition. As well, a group of words may function as a preposition. Following is a list of common prepositions: about, at, but (meaning except), into, throughout, above, before, by, like, to, across, behind, concerning, of, toward, after, below, down, off, under, against, beneath, during, on, underneath, along, beside, except, over, until, amid, besides, for, past, unto, among, between, from , since, up, around, beyond, in, through, upon, with, within and without.
The Conjunction
The conjunction is used to join words or groups of words. There are three kind of conjunctions:
coordinating, correlative
and
subordinating.
The coordinating conjunctions are as follows: and, but, or, nor and for.
The correlative conjunctions are always used in pairs. They are as follows: either/or, neither/nor, both/and, not only/but (also) and whether/or.
The subordinating conjunctions are used to begin subordinating clauses. A clause is a group of words that contains a subject and predicate and is used as a part of the sentence. A subordinate clause is a clause that cannot stand alone as a sentence in and of itself. The following is a list of the most commonly used subordinating conjunctions: after, before, provided, unless, although, how, since, until, as, if, than, when, as much as, in order that, that, where, because, inasmuch as, though and while.
The Interjection
The last part of speech is the interjection. It is a word used to express emotion and has no grammatical relation to other words in the sentence. Common examples we see used often are: Oh! Ah! Ouch! Alas!
There you go. The eight parts of speech made simple.
