What is the meaning of 'desultory'?

The word 'desultory' is best defined as lacking a definite plan or regularity. It describes actions or thoughts that are disconnected or aimless, often jumping from one subject to another without a clear or coherent objective. This term often conveys a sense of randomness and inconsistency, as in ideas that are poorly organized or pursuits that are undertaken without commitment or consistency.

In contrast, the other choices present meanings that do not align with the essence of 'desultory'. The first option suggests consistency and purpose, which directly contradicts the idea of being aimless or lacking a plan. The third choice alludes to perceptiveness, indicating an astute or insightful quality that does not relate to the disconnected nature characterized by desultory behavior. The fourth choice refers to excessive detail, which also stands in opposition to the concept of aimless or scattered focus implied in desultory contexts.
