When someone is described as vociferous, it means they are forcefully outspoken or vehemently insistent on something. This adjective is not used to describe sounds in the same way loud is—you probably won't hear vociferous used to describe a blaring quartet of trombones. But you might hear it used to describe a boisterous and noisy crowd, with vociferous in this context suggesting discord or clamor.
Abide has many meanings; it comes closest to the word tolerate when used to mean “to put up with,” a sense that most often appears in negative constructions. For instance, you might not be able or willing to abide, or put up with, dishonesty. (Wise!) Abide often appears before by, as in “She refused to abide by their rules.” Here, abide takes on a slightly different meaning of “to submit to” or “to agree to.”
An anecdote is a short account of a particular incident or event, especially of an interesting or amusing nature. Anecdotes are usually narrated or shared orally rather than written; sometimes they are offered to lend support to an idea or conclusion based on real-world experience. Unlike the word story, anecdote is not used to talk about the plot of a novel, poem, or drama.
