Is 'self-replicate' only used for living things?

No, while originating in biology, it is now commonly used for computer viruses, robots, nanomaterials, and even abstract concepts like ideas or information patterns that spread autonomously.

What is the difference between 'replicate' and 'self-replicate'?

'Replicate' often implies an external agent doing the copying (e.g., scientists replicate an experiment). 'Self-replicate' emphasizes the internal, autonomous capability of the subject to copy itself without external direction.

Can 'self-replicate' be used as a noun?

Rarely. The noun form is typically 'self-replication' (e.g., 'the process of self-replication'). Using 'self-replicate' as a noun is non-standard.

Is the hyphen necessary?

Yes, in most dictionaries and formal writing, the hyphen is used, especially when preceding a noun (self-replicating machine). It can sometimes be seen as a closed compound (self replicate) in less formal technical writing, but hyphenated is the standard.

Is “self-replicate” formal?

Self-replicate is usually formal, technical, academic in register.
