In addition to Flipside's spelling and grammar.

Another thing about grammar: Make sure you understand what a noun, verb, adjective, adverb, pronoun, and ... well, everything else is!

A noun: A person, place, or thing.

A pronoun (I googled it... got a nice little example out of it): The part of speech that can take the place of a noun in a sentence and function as a noun. In the sentence "Mr. Rice spoke to Tom and offered him a job," "him" is the pronoun; it takes the place of "Tom."

A verb: Describes an action or a state of being.

An adverb (took me years to actually understand this): An adverb provides more detail to another adverb, a verb, or an adjective. Words like 'beautifully', 'very', and 'quickly' are adverbs.

An adjective: It describes something. More specifically, it describes a noun or pronoun but isn't one itself. It's like a wannabe. And I will add this nice example from google: Adjectives either come before a noun or after linking verbs (eg be, seem, look).

A preposition: This type of word relates a noun to a pronoun. For example... a little trick I know is using the 'Mountain'. I am at the mountain ('at' being the preposition). I am between the mountain. I am in the mountain. If it makes sense to say it, in relation to a mountain (:O mountain is a noun!), then you're all good.
