Classification — valid base word + “-ship” vs accidental wordplay: Identify the odd pair: Flag : Flagship, Court : courtship, war : Worship, Friend : Friendship.

Introduction / Context:
This item tests morphological awareness: three pairs correctly show a meaningful word formed by adding the suffix “-ship” to the base. One pair seems similar orthographically but is actually a different word formed by a different process (not base + “-ship”). Spotting the false decomposition is the key.

Given Data / Assumptions:

• Flag → flagship (a lead ship or principal example).
• Court → courtship (the act of seeking a partner; also wooing behavior).
• Friend → friendship (state of being friends).
• war → worship (not “war + ship”; “worship” derives from a different root and is unrelated to “war”).

Concept / Approach:
Check whether removing “ship” from the right-hand word leaves the exact left-hand base. If yes and the remaining base is semantically connected, the formation is valid. If not (as with “worship”), the pair is a deceptive look-alike rather than true suffixation.

Step-by-Step Solution:
1) Flagship → “flag” + “ship” → valid morphological formation.2) Courtship → “court” + “ship” → valid.3) Friendship → “friend” + “ship” → valid.4) Worship ≠ “war” + “ship”; removing “ship” yields “wor,” not “war.”

Verification / Alternative check:
Try dictionary reasoning: “worship” originates from “worth-ship,” historically unrelated to “war.” This confirms that option C is not a simple base + suffix construction, making it the outlier.

Why Other Options Are Wrong:
They all demonstrate legitimate base + “-ship” morphology, consistent with the intended pattern.

Common Pitfalls:
Being misled by visual similarity (“war” vs “wor”). Morphology depends on true base forms, not surface resemblance.

Final Answer:
war : Worship
