Odd One Out — Big, Small, and Tiny denote physical size; Trivial denotes low importance. Identify the odd adjective by semantic domain.

Introduction / Context:
Semantic classification tests whether words belong to the same conceptual field. Three refer to magnitude of size; one refers to significance/importance.

Given Data / Assumptions:

• Big, Small, Tiny: adjectives of physical size/extent.
• Trivial: adjective of importance (insignificant), not size.

Concept / Approach:
Group by semantic domain: size vs importance.

Step-by-Step Solution:
Big → size.Small → size.Tiny → size.Trivial → importance (not size) → outlier.

Verification / Alternative check:
Comparatives/superlatives: big/bigger/biggest etc. map to size; trivial does not form size gradations but importance gradations (trivial vs crucial).

Why Other Options Are Wrong:

• Big, Small, Tiny: all measure physical extent.

Common Pitfalls:
Equating “small” with “trivial” metaphorically; in literal classification, domains must match.

Final Answer:
Trivial
