Key Concepts & Vocabulary
TermDefinitionExample
AdjectiveA word that describes a noun (a person, place, or thing). Adjectives tell us more about the noun, like its color, size, or shape.The *big* dog barked. ('big' describes the dog)
NounA word for a person, place, or thing.The big *dog* barked. ('dog' is the noun)

Key Rules & Conventions
The 'Before the Noun' Rule
adjective-adjective + noun
Use a hyphen to connect two describing words when they come directly BEFORE the noun they are describing. The hyphen shows they are working together as a single team.
The 'One Idea' Rule
word + word = one single description
The hyphen acts like glue, sticking two words together to create one single idea. For example, a 'light-blue' car is one specific color, not a car that is both light in weight and blue in color.
The 'No Hyphen After' Rule
noun + is/was + adjective and adjective
Do not use a hyphen if the describing words come AFTER the noun. When they are not right in front of the noun, they don't need to be joined together.
