Classification – Odd one out (parts of speech) Among the following, three are verbs denoting actions; one is a noun. Identify the noun as the odd one out.

Introduction / Context:Parts-of-speech classification is a common verbal reasoning theme. The majority class here is action verbs; the single outsider is a noun naming a concept/state rather than an action.

Given Data / Assumptions:

• Write (verb)
• Read (verb)
• Learn (verb)
• knowledge (noun; abstract)

Concept / Approach:Label each word’s grammatical role. Choose the one that is not a verb.

Step-by-Step Solution:Write → action verb.Read → action verb.Learn → action verb.knowledge → abstract noun → odd one out.

Verification / Alternative check:Insertion test: “to ___” fits verbs (to write, to read, to learn) but not “to knowledge,” which is ungrammatical, confirming noun status.

Why Other Options Are Wrong:

• Write, Read, Learn → verbs.
• None of these → exactly one noun exists (knowledge).

Common Pitfalls:Capitalization or treating “knowledge” as proper. It is a common noun here; case does not change the part of speech.

Final Answer:knowledge
