Key points
- Noun adjuncts remain singular; Pronoun vs Adjective distinctions; Preposition vs Adverb particles; Conjunction functions.
Applied Word Functions and Exceptions
Competitive examinations frequently test whether candidates can distinguish functional shifts where nouns act as adjectives, pronouns disguise as adjectives, or prepositions operate as adverbs or conjunctions.
1. Noun Adjuncts (Nouns Used as Adjectives)
When a noun modifies another noun, it acts as an adjective (noun adjunct) and must generally remain singular.
Example
Incorrect: He stayed in a five stars hotel.
Correct: He stayed in a five-star hotel.
2. Pronoun vs. Pronominal Adjective
Demonstrative, distributive, and interrogative words act as pronouns when used alone, but become adjectives when directly qualifying a following noun.
- Pronoun: This is my ancestral house.
- Adjective: This house belongs to my grandfather.
- Pronoun: Each of the candidates received a certificate.
- Adjective: Each candidate received a certificate.
Key Rule
Prepositions always govern a noun, pronoun, or noun phrase (its object). If the word does not have an object and modifies a verb, it functions as an adverb particle.
Example
Preposition: The boy fell down the stairs. (Stairs = object)
Adverb: Please sit down. (Modifies the verb 'sit')
Exam Tip / Common Error
Do not confuse coordinating conjunctions with prepositions. For is a preposition when followed by an object noun (He waited for me), but a conjunction when joining independent clauses (He stayed back, for it was raining).
