Grammar notes

Grammar is a set of structural rules that is in control of the way that language works, there are three parts or aspects of grammar which are word classes, syntax and morphology.
Word classes are the roles that a word would play in a sentence.
Syntax is the set of rules that control where each word class can appear in a sentence.
Morphology describes the building blocks of individual words.

There are eight main word classes:
nouns which are naming words such as the name of a person, place or thing.

adjectives which describe nouns so what the person or thing looks like or is like.

verbs which are doing words telling you to do something like jump.

adverbs which describe verbs like the word incredibly.

pronouns which take the place of nouns such as you, they, him or me.

conjunctions are connecting words that connect sentences for example and, or, but, because.

prepositions which define relationships between words in terms of time space or direction.

and finally determiners which give specific kinds of info about the nouns like a, the, two, his.

Word classes can take different positions in a sentence but there are rules about how they go and work with one another. it is straight forward for when a sentence doesn't make sense the order is wrong. Grammar rules effect word formation, (morphology) because extra parts sometimes has to be added to words to change things like number or tense. the extra parts are called inflections.
 Tense: events that happen in the past are usually described in past tense, sometimes however in both spoken or written discourse, past events are described using present tense forms. There is a clear sense that time has passed since the even happened, you can tell this by the words that are used.
Plurals: by using plurals in a sentence it can increase the scale of the scene or what is happening,
Adjectives: they are a good way to influence and persuade your target audience as they can be exaggerated especially combining plurals and adjectives.
