What does mutative mean?
Mutative is an uncommon adjective meaning relating to, causing, or characterized by mutation. In its best-known technical sense, it describes an agent, process, or influence capable of producing a genetic change, as in references to the mutative effects of radiation or chemicals. The word can also convey a tendency to undergo mutation, although mutagenic is usually preferred when the intended meaning is specifically “capable of causing mutations.” Mutative belongs primarily to biological and scientific language and is less common in general prose than mutable, which means able to be changed. Although the two words sound related and can overlap in loose usage, they emphasize different ideas: mutative focuses on mutation and its effects, while mutable focuses on the possibility of change itself.

- Relating to or causing mutation.
- Characterized by mutation or a tendency to mutate.

"The compound has a strongly mutative effect on DNA."
"Researchers examined the mutative properties of the chemical under controlled conditions."
Mutative is biology's reminder that some changes are not merely possible—they actively provoke mutation.

Where does mutative come from?
Mutative was formed in English from mutation with the suffix -ive, a combining form associated with action, tendency, or relation. Mutation ultimately comes through French from Latin mutatio, a noun derived from mutare, meaning “to change.” The same Latin root also underlies mutate and mutant, which share the concept of alteration but are not inflected forms of mutative.
How mutative is actually used
This is a relatively uncommon formal or technical term, used chiefly in biology, genetics, and related scientific contexts. In contemporary usage, mutagenic is often more natural when describing something that causes genetic mutations.
Easily confused with mutative
Mutable means able to be changed, whereas mutative more commonly means causing or relating to mutation.
