Concept:
Vocabulary evaluation based on contextual definitions or standard lexical semantics.
• Target Word: "idler"
Step 1: {Lexical analysis of the word.}
The noun "idler" comes directly from the root adjective "idle," which describes someone who avoids work, remains inactive, or spends time doing nothing productive. Therefore, an idler denotes someone who habitually avoids effort or operational tasks.
Step 2: {Evaluating definitions.}
• an active person: An exact antonym to the concept of idling.
• an enthusiastic person: Refers to someone showing intense excitement, completely unrelated to work avoidance.
• a lazy person: Directly matches the definition of an idler as someone who avoids physical or mental exertion.
• a player: Refers to a participant in a game or drama, which does not capture the meaning of passivity.
Step 3: {Final Check.}
The choice matching the definition is option (3).
