Determiners:
* Specify: They tell us *which* noun we're talking about.
* Quantify: They tell us *how much* or *how many* of the noun.
* Possess: They indicate *who owns* the noun.
* Position: They determine the *order* of the noun.
Examples:
* Articles: *the, a, an*
* "The dog" (specific dog)
* "A dog" (any dog)
* Demonstratives: *this, that, these, those*
* "That book" (specific book)
* Quantifiers: *some, any, few, many, all, every*
* "Some apples" (unspecified amount)
* "All students" (all students)
* Possessives: *my, your, his, her, its, our, their*
* "My car" (car belonging to me)
Adjectives:
* Describe: They provide information about the *qualities* of the noun.
* Modify: They change the meaning of the noun by adding detail.
Examples:
* Color: *red, blue, green*
* "Red car"
* Size: *big, small, tall, short*
* "Big house"
* Shape: *round, square, long, thin*
* "Round table"
Key Differences:
* Placement: Determiners usually precede the noun, while adjectives can appear before or after the noun (with some exceptions).
* Function: Determiners specify or quantify, while adjectives describe.
* Type: Determiners are a closed class (a limited set), while adjectives are an open class (constantly expanding).
Example:
* "The big red car"
* The: Determiner (specific car)
* Big: Adjective (describes size)
* Red: Adjective (describes color)
* Car: Noun
In summary, determiners provide essential information about the noun, while adjectives add details and descriptions.
