Sequester

sih-KWES-ter

Definition

(verb) To isolate or remove something—or someone—from others; to set apart.

Example

During the trial, the judge decided to sequester the jury to prevent outside influence.

Word Origin

Sequester comes from the Latin sequestrare, meaning “to surrender something to a trustee” or “to set aside.” Over centuries, the meaning shifted toward isolation and removal—particularly in legal, environmental, and scientific contexts where something is intentionally kept separate.

Fun Fact

In environmental science, carbon sequestration refers to the process of capturing and storing carbon dioxide to reduce greenhouse gases. Forests, wetlands, and even certain types of soil act as natural carbon banks, quietly pulling CO₂ out of the atmosphere and locking it away. This idea of “pulling something out of circulation” connects directly back to the core meaning of the word.

Cerebral

suh-REE-brul

Definition

(adjective) Relating to or requiring the use of the intellect rather than emotions or instincts; appealing to the mind over the senses.

Example

The film was cerebral in a way that divided audiences cleanly — those who loved puzzling it out and those who just wanted someone to explain what happened.

Word Origin

Cerebral derives from the Latin cerebrum, meaning “brain,” itself possibly related to the Greek kara meaning “head.” The same root gives us cerebellum — the smaller structure at the base of the brain — and cerebrovascular, the medical term for anything relating to the brain’s blood supply. It entered English in the early 19th century, initially as a purely anatomical term before acquiring its broader figurative sense of anything that engages the intellect more than the emotions or senses.

Fun Fact

The left brain/right brain theory — the popular idea that cerebral, analytical people are “left-brained” while creative, emotional people are “right-brained” — is one of neuroscience’s most persistent and most thoroughly debunked myths. Brain imaging studies consistently show that complex tasks engage both hemispheres simultaneously, and no reliable evidence supports the idea that individuals preferentially use one side. The theory originated from legitimate 1960s research on split-brain patients — people whose corpus callosum had been severed — but was dramatically oversimplified as it filtered into popular culture. Most neuroscientists consider it a textbook example of how a genuinely interesting finding becomes a completely misleading cultural myth.
