“Latent” means “hidden”. It doesn’t mean “slow” or “late”. I really hate this barbarous abuse of language.
It appears you are seeking reasons to hate.
Latent is an adjective describing something that exists, is present, or is dormant—like a hidden talent, a resting virus, or a quiet disease stage—waiting for the right conditions to become active or visible.
Latency is a noun that refers to the state of being latent, or more commonly, the time delay or lag between a cause and an effect (such as the time it takes for data to travel across a network or for a disease to reactivate).
