The terms determiners and adjectivals both refer to words or groups of words that provide additional information about nouns, but they serve different roles in a sentence. Here’s how they differ:
Determiners
Determiners are words that come before a noun and provide information about which noun you are referring to, or how many or how much of the noun there is. They help to define the noun more clearly in terms of specificity or quantity. Determiners are essential for clarifying the noun they precede.
Types of Determiners:
- Articles: "a," "an," and "the."
- The car (specific car, previously mentioned or known)
- A dog (any dog, not specific)
- Demonstratives: "this," "that," "these," "those."
- This book (a specific book near the speaker)
- Those people (specific people further away)
- Possessives: "my," "your," "his," "her," "its," "our," "their."
- Her car (the car belonging to her)
- Their house (the house belonging to them)
- Quantifiers: "some," "many," "few," "all," "more," "most," etc.
- Some apples (an unspecified amount)
- Many students (a large number)
- Interrogatives: "which," "what," "whose."
- Which book do you want?
- Whose keys are these?
Key Role of Determiners:
- Determiners define the reference of the noun.
- They help to answer questions like which one?, how much?, how many?, and whose?
Adjectivals
Adjectivals are words or phrases that modify or describe a noun by adding more detail, particularly in terms of its qualities, characteristics, or attributes. These can be adjectives or adjectival phrases. Unlike determiners, adjectivals typically provide more descriptive information rather than clarifying reference or quantity.
Types of Adjectivals:
- Adjectives: Words that describe the qualities of the noun.
- The red car (Here, "red" describes the color of the car.)
- Adjectival Phrases: A group of words that act as an adjective to modify the noun.
- The man in the blue suit (Here, "in the blue suit" modifies "man.")
- Participial Phrases: A verb form acting as an adjective.
- The excited children (Here, "excited" describes the children’s state of being.)
- Prepositional Phrases: Sometimes prepositional phrases function as adjectivals.
- The woman with the glasses (Here, "with the glasses" describes the woman.)
Key Role of Adjectivals:
- Adjectivals describe the attributes or qualities of the noun.
- They help answer questions like what kind?, which one?, or how? in a more descriptive way.

Example Sentences:
- Determiner: I have three apples.
(The determiner "three" answers the question "How many apples?") - Adjectival: I have red apples.
(The adjectival "red" describes the color of the apples.) - Both: I have three red apples.
(Here, "three" is the determiner (how many?), and "red" is the adjectival (what kind?)).
Summary:
- Determiners clarify reference and quantity (which, how much, whose).
- Adjectivals provide additional descriptive information about the noun (what kind, how, etc.).
