What does dormant mean?
Dormant describes something that is temporarily inactive or suspended, with the strong implication that it can wake up or resume activity. In biology, animals and plants are said to lie dormant during winter or periods of drought, conserving energy until conditions improve; volcanologists reserve the term for volcanoes that are quiet now but could erupt again, as distinct from extinct ones that never will. Beyond nature, dormant applies to anything latent or unexercised: a talent lying dormant since childhood, a bank account untouched for years, or a legal claim awaiting action. The word comes from Latin dormire, 'to sleep', so at its heart it always carries the image of sleeping rather than dying. That nuance makes it valuable — where 'dead', 'idle', or 'gone' imply finality, dormant promises potential return, lending the word a quietly hopeful tone even when describing something still and silent.
adjectiveTemporarily inactive, suspended, or in a state of reduced activity, especially with the capacity to become active again later. Also used of a feeling, right, or possibility that exists but has not yet been expressed or acted upon.
- (of an animal or plant) in a state of suspended biological growth or activity, such as hibernation or seasonal rest
- (of a volcano) not currently erupting but expected to be capable of erupting again
- (of a feeling, idea, talent, or quality) present but not active, visible, or developed
- (of a business, account, law, or right) temporarily not in use or operation
"The volcano has been dormant for centuries, but geologists warn it may erupt again."
"Many seeds remain dormant through winter and sprout only when the soil warms."
"Her talent for painting lay dormant for years before she finally returned to it."
A dormant volcano isn't dead — it's just holding its breath, and some have roared back to life after thousands of years.

Etymology of dormant
Dormant entered English in the late Middle Ages from Old French, ultimately deriving from Latin dormire, meaning 'to sleep'. It shares this root with dormitory (a room for sleeping), dormouse (a long-sleeping rodent), and related words like dormant's noun form dormancy. The word originally described sleepers and sleeping states before broadening to cover any suspended activity, including the geological and figurative senses familiar today.

How dormant is actually used
Dormant is somewhat formal in register but common across scientific writing (biology, volcanology), legal contexts, and figurative everyday speech. The phrase 'lie dormant' is the most idiomatic verb pairing. It carries no strong positive or negative connotation — it simply implies temporary suspension rather than permanent death.
