What does latent mean?
Latent describes something that exists or is possible without yet being visible, active, or fully developed. The word is especially useful when something is present in an incomplete or dormant state: a latent infection may remain inactive, a latent defect may not yet cause failure, and latent talent may exist without having been recognized or expressed. In psychology and education, latent ability refers to potential that has not yet appeared as developed performance. Because latent implies more than simple absence, it suggests that change may become apparent later. The term is common in formal, academic, scientific, and technical writing, though its meaning is broadly understood. Its Latin origin, from a word meaning “to lie hidden,” captures the central idea well: what is latent is not necessarily gone; it may simply be concealed, inactive, or waiting to emerge.
Present or potential but not yet visible, active, or apparent; existing in a concealed or undeveloped state.
"The investigators uncovered a latent error in the system."
Common in formal, academic, scientific, and technical usage; it often implies that the thing may later become apparent or active.
A person whose abilities, traits, or potential have not yet been fully developed or revealed.
"The academy was looking for latents with unusual creative ability."

The plural is uncommon; latent is normally used as an adjective.
"The coaches recognized several latents among the young players."
Latent comes from a Latin word meaning “to lie hidden”: something dormant can still be there—and still have consequences.

Where does latent come from?
The English adjective entered use in the early 17th century from Latin latentem, the accusative singular form of the present participle latens. The related Latin verb lateō meant “to lie hidden” or “to lurk,” giving latent its sense of something present but concealed or not yet apparent. The related English noun latency continues the same Latin stem and refers to a condition or period of being hidden, delayed, or inactive.
