Latent and dormant both describe something that is not obvious right now, but they are not the same.
Latent means present but hidden, undeveloped, or not yet detectable. The thing exists, even if you cannot see its effects yet. You often see this word in science, medicine, psychology, and formal writing.
Example: The virus remained latent for years.
Dormant means inactive for now, often with the idea that activity could return later. It suggests a resting or sleeping state rather than something merely hidden.
Example: The volcano has been dormant since 1846.
- Use latent for something concealed, potential, or not yet expressed.
- Use dormant for something temporarily inactive or at rest.
A helpful contrast is this: a person may have latent musical talent, even if nobody has noticed it yet. A business, however, might be dormant if it has stopped operating for a time. If you mean hidden potential or an unseen condition, choose latent. If you mean temporarily inactive, choose dormant.
