Foreign. It's Merriam Webster's Word of the Day for July 9th. Today's word is tacit, spelled T A C I T. Tacit is an adjective. It's a formal word used to describe something that is expressed or understood without being directly stated. Here's the word used in a sentence from Boston.com where modern documentaries are slick productions filled with preconceived notions, embedded narratives, and tacit approval of their subjects, Frederick Wiseman's work is slow, contemplative, and refreshingly slant free. In the first chapter of Emily Bronte's Wuthering Heights, the narrator, Mr. Lockwood, recounts warily encountering three dogs. Although he was sure to sit still, he admits in retrospect that imagining they would scarcely understand tacit insults, I unfortunately indulged in winking and making faces at the trio. One subsequently leapt onto his knees in fury. His tacit insults were, by the relevant definition of tacit, not expressed with words but in this case facial expressions. Tacit can also mean implied or indicated, as by an act or by silence, but not expressed. A tacit agreement is one that is understood without being directly stated. And if you have your parents tacit approval to borrow the car, or if your children have your tacit approval, you don't have to ask or be asked. Tacit traces back to the Latin verb takeere, meaning to be silent, which is also the answer of the English adjective taciturn, used to describe someone who tends to be quiet with your word of the day.
