Odd One Out — Uncle, Nephew, and Brother are gendered male terms; Cousin is a gender-neutral kinship term. Identify the odd relationship term and explain.

Introduction / Context:
Kinship terminology can be grouped by whether the word encodes gender. Three options explicitly denote male relations; one is gender-neutral.

Given Data / Assumptions:

• Uncle: male sibling of a parent or their male spouse.
• Nephew: a brother’s/ sister’s son (male).
• Brother: male sibling.
• Cousin: gender-neutral term for a child of one’s aunt/uncle.

Concept / Approach:
Identify which label does not encode male gender in its form/meaning.

Step-by-Step Solution:
Uncle → male-specific.Nephew → male-specific.Brother → male-specific.Cousin → gender-neutral → outlier by gender coding.

Verification / Alternative check:
Generation test is weaker (uncle is elder generation; nephew is younger; brother/cousin same generation) and does not yield a single outlier. Gender-coding does.

Why Other Options Are Wrong:

• Uncle, Nephew, Brother: all explicitly male relations.

Common Pitfalls:
Assuming “cousin brother” colloquialism implies gender; standard English “cousin” is gender-neutral.

Final Answer:
Cousin
