Mendacious is another way of describing something containing a falsehood or deception. It can also be a way to say someone is lying without saying they are lying. It is a softer form suggesting that someone is often wrong without being accusatory. Another example might be someone noted for telling “tall tales” or being prone to exaggeration in stories.
“Companies engaging in mendacious advertising often get sued.”
“Her mendacious reporting on the story contained many ‘facts’ she knew to be false.”
“Johnny was known for his mendacious claims of success during his career.”
“Today, many news agencies engage in mendacious reporting that we call ‘fake news.’”
The word ineffable denotes something that is too extreme or great to be expressed in words. It is a concept that can truly leave one speechless. It has a feeling that is so profound and overwhelming that it defies any attempt at verbal expression.
Think of something that is indescribable or unspeakable. At times, you might also use ineffable to describe something taboo.
According to the Oxford Dictionary, the word has its origin in Middle English, French, and Latin. Here, we combine “in,” meaning “not,” and “effabilis,” meaning “spoken.”
“As Sonny caught sight of his fiancée walking down the aisle, he was overcome with an ineffable sensation that words could not do justice.”
“When the astronauts first realized that there would be an ‘earthrise’ on the moon, they were overwhelmed with an ineffable sense of awe.”
Of course, it is possible to combine ineffable and mendacious into sentences with a little effort and thought.
“The ineffable beauty of the painting was marred only by his mendacious claim to have painted it in one day.”
“Her mendacious storytelling became so extreme that others began to accept them as ineffable hogwash.”
