Being able to identify different word types is important in order to use subject terminology.
NOTE: Be aware that the same word can have more than one 'type' depending on how it is used in a sentence. For example:
"The burning building." - Here, "burning" is an adjective as it describes the building.
"The building was burning." - Here, "burning" is a verb as it tells us what the building is doing.
The things/objects in a sentence.
"The dog barked at the door."
The action word in a sentence.
"The man ran across the road."
A word that describes a noun.
"The fluffy cloud stood alone in an otherwise clear sky."
A word that describes the verb/adjective.
"The woman shouted loudly."
A word that replaces a noun.
"He wasn't happy with us."
A word/phrase that tells us about the location of a noun.
"The ball flew over the fence and somehow landed under the table."
