Classification – Pick the odd one out based on part of speech and exact lexical form. Three words are adjectives meaning “more than enough,” while one is a noun (and thus does not belong). Which option is different? Options: Ample, Copious, Plentiful, Abundance.

Introduction / Context:
Verbal classification often hinges on identifying the grammatical category or exact sense alignment of words. Here, three options are adjectives synonymous with “plenty,” while one option is a noun referring to the state of having plenty. Recognizing parts of speech quickly isolates the odd item.

Given Data / Assumptions:

• Ample: adjective (sufficient, more than adequate).
• Copious: adjective (abundant in supply or quantity).
• Plentiful: adjective (present in large amounts).
• Abundance: noun (a very large quantity of something).

Concept / Approach:
Determine the dominant property among the majority—here, adjective form with similar meaning—and identify the single option that differs in grammatical role (noun) even though semantic fields are related.

Step-by-Step Solution:
Step 1: Mark parts of speech for each option.Step 2: Find that Ample, Copious, and Plentiful are adjectives.Step 3: Note that Abundance is a noun; therefore, it breaks the pattern.

Verification / Alternative check:
Substitute each before a noun (e.g., “ample time,” “copious notes,” “plentiful resources”). “Abundance time” is ungrammatical without “of” (“an abundance of time”), confirming it is not an adjective.

Why Other Options Are Wrong:
Ample: adjective, fits group.
Copious: adjective, fits group.
Plentiful: adjective, fits group.

Common Pitfalls:
Do not let semantic similarity overshadow grammatical category differences; part of speech is decisive.

Final Answer:
Abundance
