Fun Fact
“Vestigial” comes from the Latin word vestigium, meaning “footprint” or “trace.” Initially referring to physical remnants, it evolved to describe anything lingering or diminished. In evolutionary biology, it describes traits like the human tailbone or appendix, which no longer serve their original purpose but offer fascinating insights into our species’ history.
(noun) The range of one’s knowledge, understanding, or awareness.
Quantum physics lies far beyond my ken, no matter how many articles I read.
Ken comes from Old English cennan, meaning “to know” or “to make known,” and is closely related to Middle English and Scots usage where it meant knowledge, perception, or recognition. Over time, the word narrowed to describe the limits of what someone knows or understands, which is why it’s often used today in phrases like “beyond my ken.”
