Classification (morphology): Three pairs are formed by adding the suffix “-ship” to a base word; one is not a suffixal formation but an unrelated word. Identify the odd pair.

Introduction / Context:
Morphological classification evaluates whether a derived word genuinely comes from a base via a productive suffix. In English, the suffix “-ship” creates abstract nouns meaning state, condition, rank, or collective relationship (for example, friendship, leadership). In this question, three options involve words that contain the letters “ship” at the end, but only those that are true suffixal derivations from the given base should be considered consistent. The challenge is to detect the pair where the right hand word is not a true “base + ship” formation.

Given Data / Assumptions:

• Pairs: Flag : Flagship, Court : Courtship, War : Worship, Friend : Friendship.
• “-ship” as a suffix yields nouns like friendship (friend + ship) and courtship (court + ship).
• “Flagship” is historically a compound noun referring to the ship carrying the commanding officer’s flag; synchronically it behaves as a lexicalized compound, not a standard suffixal abstract noun.

Concept / Approach:
Check if the right hand term transparently equals left hand base + the suffix “-ship” with an abstract relational sense. Reject cases where the letters “ship” are present but the meaning or formation does not align with suffixal usage (for example, worship does not equal war + ship).

Step-by-Step Solution:

Verification / Alternative check:
Paraphrase each right hand term: friendship (state of friends), courtship (period of courting), flagship (the lead vessel), worship (act of reverence). Only worship has no morphological or semantic connection to war.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming that any word ending in the letters “ship” must be base + suffix. Always test for semantic transparency and etymology when possible. Visual similarity can be deceptive.

Final Answer:
War : Worship
