Word of the Day - Parenthetical

[debodun]

Parenthetical (adjective) - the quality of information that's secondary to the main point, often as an aside, explanation, or qualification, like a digression inserted into speech or writing, marked by commas, dashes, or parentheses, which could be removed without changing the core meaning of the sentence.

In the sentence, "Marie Curie, a pioneering chemist and physicist, won two Nobel Prizes.", the phrase "a pioneering chemist and physicist" is the parenthetical phrase.
