Identify the odd word: Three words describe extent/measurement in the vertical or linear sense (height/length), while one relates to brightness/illumination. Choose the mismatching word.

Introduction / Context:
Verbal classification often groups words by domain of meaning. Here, three adjectives belong to physical extent (height/length) while one belongs to light/visibility.

Given Data / Assumptions:

• Words: Long, Tall, High, Dim.
• Category 1: measurement of extent; Category 2: brightness.

Concept / Approach:
Map each word to its primary semantic field and separate the outlier that does not describe linear or vertical extent.

Step-by-Step Solution:

Verification / Alternative check:
Try substituting context sentences: “a long rope,” “a tall building,” “a high wall” are natural; “a dim building” shifts to lighting, confirming different semantics.

Why Other Options Are Wrong:
Long, Tall, and High share the measurement domain.

Common Pitfalls:
Assuming High and Tall are always interchangeable. They are related, but both stay within the extent/height family, unlike Dim.

Final Answer:
Dim is the odd word (brightness term, not an extent term).
