The term 'hidden; dormant' can be summarized by the word 'LATENT'. LATENT refers to something that is present or potential but not evident or active. It is often used to describe a hidden talent or ability that has yet to be realized. In psychology, LATENT refers to an unconscious impulse or desire that is not expressed in behavior. In biology, it is used to describe a gene or trait that is not expressed in the phenotype of an organism.
