Hidden is the past participle of hide, as in, I’ve hidden the presents, but also an adjective often used with abstract nouns to suggest something present but not apparent or not perceivable: hidden talent; hidden meaning. Latent, which derives from a Latin verb meaning “to lie hidden,” can be a strong synonym for hidden. Latent refers to a power, ability, or emotion that is present as a potential, but is not yet apparent, fully developed, or openly expressed. A talent can lie or remain latent, hidden even from the possessor of it, if there has been no opportunity to develop or use it. A perceptive therapist might observe that a client’s frequent use of sarcasm reveals latent anger.
