What does tardive mean?
Tardive means late, delayed, or occurring after the expected time. Its most recognizable use is in medical language: tardive dyskinesia is a movement disorder associated with prolonged exposure to certain antipsychotic drugs, while tardive parkinsonism describes a similarly delayed form of parkinsonism. These conditions can emerge after months or years of treatment and may persist even after the medication is discontinued, which makes the word's implication of delayed onset especially apt. Outside medicine, tardive is a formal alternative to late or belated and may characterize a reply, decision, development, or other event that arrives too late to be timely. The related noun refers to a late arrival or something that develops late. Although “tardy” is more common in general usage, tardive has a distinctive clinical resonance and is worth knowing because it names effects that can remain hidden for a long time before becoming apparent.
Late in development or occurrence; delayed, especially after an expected or usual time.
"The drug was associated with tardive involuntary movements in some patients."
Especially common in medical terminology, but also used formally for responses, decisions, and developments that arrive late.
A person or thing that arrives or develops late.
"The final tardives joined the procession long after the procession had begun."
The noun is much less common than the adjective and has a literary or dated quality.
The plural is grammatically regular but is rarely needed because the noun itself is uncommon.
"Three tardives eventually arrived to complete the work."
The “late” in tardive can arrive years late—especially with tardive dyskinesia, a movement disorder that may appear after prolonged medication use.

Where does tardive come from?
Tardive entered English in the 19th century from French, where tardif means “late” and tardive is the corresponding feminine form. These forms continue Latin tardus, meaning “slow” or “late,” which also underlies cognates including tardy, tarditude, and tardigrade.
How tardive is actually used
Tardive is formal and comparatively uncommon in everyday speech. It is especially associated with medicine, as in tardive dyskinesia and tardive parkinsonism, where it describes a condition appearing after exposure to a drug or after an initially stable period. The noun is considerably rarer than the adjective.
